EHX Magnum 44 Pedal Amplifier

[bifurcation]

Yeah, some of these seem crazy for the price: https://www.aliexpress.com/item/32830972522.html

Seems like it might be worth it to drop $10 and build a Son of Ben to put in front of it.

(Note: I was drawn to the one in the link because I'm thinking about doing stereo guitar with pitched down signal running into a bass cab.)

EDIT: I just realized that third channel is useless, since it's for subwoofer, its range is 10hz - 180hz

I think both of these are excellent ideas...especially the first

Thought I want less power. I found some 10W, 9V LM386-based amps for a couple bucks. I'd like to see if I can get the TH Customs amp to work (period), but I might get one of these just for the space saving alone (the caps on the one I built are HUGE).

Heh, ever since we talked about the TC Mimiq I've been thinking running one into a couple Magnum 44s out into a couple 2x12s...

I run a similar setup: pedalboard, two 'stompbox' amps and two speakers. I love it.

I'm currently building an 8-channel signal looper kit, and I think this is what my doom pedalboard setup will be.

Hey, that's cool! I see your sub out- that's something I've always wanted to try.

Digging up this thread again.
I'd also like to see a simple DIY amp along the lines of the Runoffgroove Ruby / Noisy Cricket - but a bit more powerful than half a watt.
I'm in need of a practice amp, something nice and easy.

These guys have some cool projects...I have that bundle but haven’t built it yet.

I use TPA3118 module to make 60w power amps. Looks pretty?

Have anyone looked at this: https://circuitsalad.com/2017/10/31/stomp-amp-with-improved-tone-stack/

Seems like it is in line with this thread.

I have one of those TPA3118 modules on the way, we'll see if we can come up with some sort of interface for it.

First prototype is built and tested. I will call it a success.

I used a Tyrian as a preamp, plugged into my Twin cab (2x12)....

The volume on tap is insane, especially considering I was powering both from a single 9V 1 Spot wall wart supply.

 

[Mike McLane]

I need one NOW!! In my post on the other TPA3118 thread, instead of a "volume" knob consider a rotary switch with power step downs so output can be tailored to speaker ratings. If you have a Celestion Blue you don't want to blow it out cause you didn't have a sense of where 15W output is.

Thanks for showing this off!

I think the small pedal sized power amps are very cool.

Has anyone ever made a similar in size Class D power amp that is powered by 3 prong AC plug (like Quilter)?
