What amplifiers do you like for testing how a pedal design/modification sounds?

[PapaBear]

It varies for me depending on what I have around. I lean towards tweed and Marshall sounds so that's what I use. Recently it's been a 50W plexi combo and a Brown Deluxe, both home made.

I do occasionally plug into my Marshall Bluebreaker RI

I have about 9 amplifiers and I still insist on using my Scarlett’s 2i2 for testing out my builds. I’m so lazy.

I start by playing with my Johnson.


Then, thru a MonoPrice "Stage Right" 15W 12" tube amp; an old Peavy 12" Solid Stat amp, and finally thru a Vox MV-50.

My main thing is dead clean fretless bass and I have a DIY 500 watt amp and AudioKinesis cab that's as close to a reference grade FRFR rig as I can afford and/or have space to accommodate. That serves me well for acoustic instruments too. I use a little bit of room correction EQ on the amp and that's it, typically. EQ pedals and onboard preamps are mostly what I build, so an amp with a lot of baked in sound is mostly just counterproductive. "Boring" is good sometimes, IMNSFHO.

For electric guitar I'd much rather do drive and OD right in the box with tubes, personally. So I'll make a new tube one eventually, and just be (somewhat) content with modelers for now. Time modulation EFX are the most interesting pedals for my electric guitar use cases, and testing those through my clean rigs works just fine for me.
