The jacks I use come with isolation washers:

I'll try them out on my next build and see if it makes a perceivable difference on this circuit.

For you? Nah. But for anybody else that wants to use my PCBs, here's the mounting holes. ;) ;)

I finally got around to recording a demo of the 36W version with the PCB, and Mercury Magnetics transformers: https://youtu.be/L0p04n1pSio

Or here's the shorter instagram version: https://www.instagram.com/p/CQRGsyjgwzu/

The demo also includes the "2020 Special" JoshuWah pedal series.

Thanks,
Josh

Board 1 is done. I'll do board 2 tomorrow, then clean them up and take some real photos.

Though I do find the dramatic lighting on this cellphone pic pretty funny.

Here's both amps complete:
IMG_20211112_092349_917-min.jpg

They both sound awesome, I'll be recording some demos soon enough. Both have switches on the front to mute the tremolo, and also to change the tremolo speed range. Inserting the footswitch disables the front mute switch.

I also used these photos to create a build guide that I will share after I get some feedback on it.

Thanks,
Josh

Haha, sort of...mayyyybe already sold? A local / talented musician bought my 18W Trem TMB Reverb combo that I previously shared, and wants at least another combo, maybe also the head. So we'll see if he grabs them before somebody else or not. I can probably make more. πŸ˜‰ ...but it would be a much longer wait, I'm out of cabinets and that could be a 2 or 3 month wait.

BTW- did you get my email? I sent you and a couple other members the build doc to review.

Thanks,
Josh

I just saw it. I was on holiday on Tenerife (canary islands.. nice!)
I will read and look at it thouroughly and report back. Thanks for considering my opinions!

That local talented musician.. is that the dude with the 3 pickup LP? He was surely playing it!

Hahaha, no. The guy playing the LP is a friend of mine that lives in Ohio, maybe 800 miles away? His guitar was the blue ASAT (and a couple others he brought over for new tuners/setups). The guy that owns the LP...is not quite as skilled. The good local(ish) guy is supposed to record a song with the TremTMBR, I'll share the link when he does. He has a great sound, singer/songwriter kinda thing.

Well, that blows. I just recorded 2 video demos for the 2 new amps, with an awesome boutique guitar. No audio recorded though. Whooooooooooooooops. I guess at least the playing looks cool? πŸ€·β€β™‚οΈπŸ˜‚
