Hot Mod v2?

[Davidfloyd]

All good. It is a niche, for those who want to gain up but do so with a low noise floor and retaining pure tube circuitry. Nothing against boost pedals though - I in fact did one co-designed with Robert Keeley years ago (The Time Machine Boost). First versions of those were hand wired as well, two channels of boost (JFET and Germanium). That was a fun project as well and again, in those first units were hours of building time in each one as well. Early ones had guts modeled after the original Hiwatt amps, which were works of art inside.

All said, for those that want a pure tube “gain up” this will be a fun thing for them. I’m working on an additional model next with a master volume to run it in plexi/non-master circuits - IF I can get it to sound how I’d like it to. We’ll see how it goes.

I have one with a Master volume already. Mark Cameron made it for me close to 10 years ago. He made another 15 years or so ago. He's actually bringing it to market as I type it. I made a crappy video of it a few years ago using a 100% bone stock 1967 Plexi.

Sounds good! Recheck my videos though as well (granted just done on a phone). I think the description you gave mine above may have been because of computer speakers or something? Not sure, but listen to these at the bottom. I worked very hard to eliminate the flub/overcompression and noise issues that the original HM had. Not just playing with the plate load and cathode resistors, but also adding a grid circuit to stabilize it. You can see even when I hit it with a boost - without the boost it still stays tight.

Just saying you may have been a little hard on me.

My first comment was made after you posted the first video from your sofa. Your new clips weren’t out or seen as of my first comment. I saved the clip, but out of respect I won’t post it.

I agree your later clips sound better.

Oh that one - makes sense! I actually still had a circuit tweak I made with that version. It was before I added the grid to ground circuitry. So yes, that one was closer to the sound of the original HM.
