I second that motion !

While we're on the subject, the new Way Huge Russian-Pickle would be fun to investigate, as well as other Muff based pedals from Jim Dunlop / Way Huge.
I would like to see if there are any differences between their regular Swollen Pickle MkII, the slightly smaller MkIIS and the Dirty Donny Edition or if it's all merely cosmetic.

Image start here. Input resistor is a 39k, Delete the series 1nf as these reissues have a single 500pf. Its pretty much dead ass on. The TRANSISTORS are now more common BC547C instead of the kt3102. Its a good pedal at a decent price.

Enjoy

The SLEEP lyrics on the pcb make me wanna buy one just for that tidbit alone.
Also I think the coupling caps are 104+103=110nf btw would be cool to be able to blend them for less/more.
I think I'm gonna buy myself one for Christmas. Ivr earned it.

I really like the REVV G3 pedal and their amps are a punch in the throat bad ass! Looks like you can pre-order the G4 and this is one pedal I would seriously consider buying before hearing it, just because it's a REVV.. I highly doubt they are gonna drop the ball on anything high gain..
https://revvamplification.com/product/g ... pre-order/


I would really like to see the Horizon Devices Apex Preamp but, anything from Horizon Devices would be great!
It's pricey @ $300 USD but, it has a built in cabsim and noise gate both of which seem to be quite good and of course, the high gain sounds (from what I have heard) is really damn good! At first glance it reminded me of the MXR EVH 5150 and then I scrolled to the bottom of the page and whaddya know :slap: it's made by MXR.. I am mainly interested in the gate and how they incorporated it into the preamp and I am interested in the cabsim for simplicity and really believable sound..
