NEWLY UPDATED for 2021! HOT MOD V2 EVO: The Ultimate Marshall High-Gain Plug-in Tube Modification Module!

NEW and updated for 2021! Introducing the LegendaryTones HOT MOD V2 EVO, a plug-in dual 12AX7 pure tube module specifically engineered to dramatically increase gain in Marshall amps. The HOT MOD V2 EVO requires NO chassis cutting, drilled holes, or wiring modifications to your amp – it simply and easily installs in place of the middle V2 tube position. The circuit within harnesses the power of an additional gain stage now running an additional 12AX7 tube.

Want your classic Marshall to sing with increased sustain and pure vacuum tube tone? Your tube high-gain solution is here. No solid state tricks or clipping diodes. 100% pure tube gain. The HOT MOD V2 EVO circuit was carefully designed to give you gradual increases of gain when using the amp’s preamp control. From adding a touch of sweet sustain, to full on metal, your Marshall will now have greater flexibility and deliver a wider range of tones.

With the HOT MOD V2 EVO (HMV2E), because the increased gain is created inside the amp rather than through an external pedal booster running in front of the input, the noise level of the HMV2E is dramatically reduced even at higher gain settings compared to when using an overdrive or EQ pedal used as a clean boost. Additionally, because of the HMV2E design focus was articulation with sustain, your signal can still clean up well by rolling back your guitar’s volume control. And if for some reason you still wanted more gain from an external pedal to shape or increase the signal gain further, you can still do it. You likely won’t need to, but go ahead and hit the front end of your amp with a hotter signal and the HMV2E will take it just fine!

The Marshall JMP and JCM 800 series amps from the 1970s and 1980s are legendary. And back in the day, they were getting hot rodded in numerous ways and indeed were a fantastic platform to work from. The quality of the transformers and components used in those classic amps was unparalleled. Sad to say that it’s true that they don’t make them like they used to. Now you can get many of the same high-gain Marshall tones with the simple and easy-to-use HMV2E. With the quality build and components (transformers, capacitors) found in those original early Marshall JMP and JCM 800 series amps and pure tube signal and tone that’s straight-forward and organic, the HMV2E is a great way to modernize and get the most out of your amp.

Now, there’s no need to cut up or drill into your classic amps and reduce their value. The HMV2E is a simple plug-in device that injects more gain and FUN into your Marshall! Isn’t that what it’s all about?

NEW FOR 2021! BASS BOOST/CUT WITH 2-STAGE GAIN SWITCH

The original Hot Mod V2 introduced in late 2019 was a hit, and thank you for the acceptance of it and enjoyment! But along the way, we refined the circuit and now, due to customer requests, we’ve refined it further and renamed it the HOT MOD V2 EVO as the evolution of the original Hot Mod V2.

The onboard Bass boost/cut switch is a customer request for those players who wanted to have a tighter low end. In the down position, the note articulation stays tight. When in the up position, a nice range of low-end resonance.

The 2-stage Gain switch gives high-gain boosts in both positions. In the down position it has more note clarity and attack, in the up position, even more sustain and compression. The down position is based on the tuning of the original Hot Mod V2.

We are excited to offer these updates in the HOT MOD V2 EVO.

Frequently Asked Questions

Q: Do you make a Hot Mod for the Studio series of Marshall heads like the mini JCM 800 model SC20H?

A: Yes, the new HOT MOD V2 EVO is now fully compatible with the SC/SV Studio Series Heads. Make sure to select the Standard Wired option for this application.

Q: What’s the difference between the HMV2E and the Lynch Mod?

A:  George loved the tone of the original Hot Mod V2 but then requested a special version with further customization just for him. The core drive circuit itself is identical, but the potentiometer on the Lynch Mod (LM) provides more control over how much secondary gain stage drive you can choose. When the LM is full up on gain, it is equal to the HMV2E Gain switch in the “up” position. When the LM gain is set to about 1 o’clock, it is equal to the Gain switch on the HMV2E in the “down” position. The bass switch on the HMV2E offers slightly more bass cut than the Deep switch on the LM which is tuned for slightly more warmth.

The LM is our flagship and is also fully handwired point-to-point, which raises the cost. The HMV2E is designed on a thick double-sided PCB and uses full-sized through-hole components. Both are custom designs and built in the USA by actual humans rather than machines :).

Q: Does it ship with Tubes?

A: Yes, it is equipped with two new JJ ECC83S tubes which we’ve found to be the most durable for the cathode follower position in amplifiers.

Q: Can I substitute the ECC83/12AX7 tubes for lower-gain 5751, 12AU7, etc.?

A: While we feel 12AX7 types are best, you can substitute tube types for 5751, 12AY7 and 12AT7, BUT the 12AU7 draws much more current and we do NOT advocate its use in the HMV2/Lynch Mod circuits. Also note that the cathode follower position in a Marshall can be hard on tubes, which is why we recommend use of JJ ECC83S tubes overall unless you have NOS vintage tubes on hand.

Q: Will the HMV2E work in other amps besides the JMP/JCM 800 2203/2204 models?

A: Yes, while the HMV2E will technically work in some other amp models, we’ve optimized and tuned this design specifically for Marshalls’ with master volume controls such as the 2203/2204 amplifiers. Like the original Soldano Hot Mod, it could be used in a number of other amps that use a cathode follower circuit.  Note however that some amps may not have physical clearance plus they aren’t tuned sonically for the Hot Mod V2 Evo. Visit this page for a complete list of currently compatible amps.

Q: Can I use the HMV2E with a Marshall Super Lead or other Marshall amps that don’t have a master volume?

A: Yes, while the HMV2E will work in the model 1959 and 1987 and many other similar non-master volume Marshall amplifiers, we generally recommend using the HMV2E with amps that have some type of master volume added or with an attenuator – otherwise be warned it will get loud! We also now offer a model that has increased gain, which helps for the model 1959/1987 models that don’t have the cascaded gain stage design of the 2203/2204.

Q: How does the HOT MOD V2 EVO compare in tone vs. the original Soldano Hot Mod made in the late 1980s?

A: The original Soldano Hot Mod is highly compressed right out of the gate and the preamp gain control on the Marshall also loses its full functionality because it will overcompress and cause the amp to go into feedback. The original Soldano Hot Mod has a circuit tuned for aggressive compression and becomes muddy with a high amount of bass tuned in the circuit so it can tend to lose note definition for some applications. The HMV2E in contrast is carefully tuned to maintain note articulation while still adding loads of sustain/gain while also giving players a much wider range of preamp gain control.  For a list of full compatibility, see this page.

Q: I get it, but can you build me a clone of the original Soldano Hot Mod using the new chassis?

A: Because the original Soldano Hot Mod has a much higher amount noise and less note definition, we don’t offer to clone it. However, when the Gain switch is in the “Up” position, the HMV2E has the same range of gain as the original but with lower noise, better definition, and more clarity/tightness in the low end.

Q. How about using the HMV2E with the JCM 900 series or other Marshalls?

A. The HMV2E will work in some JCM 900’s as well as other Marshalls.  Amp designs that use a cathode follower stage by design should enable the HMV2E to work. Visit the compatibility page here to see different models.

Q: My 2203/2204 has already been modified, but I’d still like to use the HMV2E. Will it work?

A: While the HMV2E is designed around stock 2203/2204 circuits, it’s hard to know exactly how it will respond to other amplifier modifications. It’s safe to say that some of the gain will still be usable and enhanced, but you may not get the full capabilities and potential of the HMV2E when it is being used in an amp that’s had unknown modifications.

Q: Will you have other models available for different amps/applications?

A: Yes, stay tuned as further designs are being engineered and tested. We are excited to offer more designs

Q: What is the warranty?

A: The HMV2E has a 3 year warranty on parts/labor from shipping date and a 90 day warranty on the tubes supplied.

Q. Can I return the HMV2E if I don’t like it?

A. YES. Customer satisfaction is very important! You can test drive the HMV2E for 14 days. If you’re not thrilled with it, send it back for a refund. I appreciate you supporting my small business and giving it a try.

Q: Can I contact you directly for further questions?

A: Sure, e-mail me at [email protected]

Some History

Back in the late 1980s, Mike Soldano of Soldano Custom Amplification released his original Hot Mod, a design based around use of rare 6C10 (and then later 6K11) tubes. These tube types added more gain much the same way that the HOT MOD V2 EVO does, but they had limitations. The tubes were long out of production, getting expensive to find, and often would become microphonic and therefore limited in capability. The original Soldano Hot Mod had lots of gain and delivered on its promise, but it was ultimately taken out of production primarily due to the challenges with finding consistent and quiet tubes.

Still, the original Hot Mod was the inspiration for the HOT MOD V2 EVO, which functions in much the same way as the original, but now has additional circuitry that further stabilizes the design, provides more clarity, and delivers a wider, more controllable range of gain on the preamp control of the amp rather than coming onto high-gain territory too quickly.  And of course the HMV2E now also uses a pair of 12AX7(ECC83) tubes that are commonly available.

With the versatility of the new HMV2E, you’re free to experiment with different tube brands as well as try 12AT7 type tubes. The Hot Mod V2 today comes supplied with tested JJ brand tubes, the same ones that major OEMs including Mesa Boogie currently use in its line of amplifiers.
