Cab-Sim/Headphone-Amp/Blender

[Marshall Arts]

This is slowly coming together. I had bad luck with the enclosure twice - it broke where I drilled the last hole (last picture, bottom left) and it had a "belly", so the toner for the lion did not stick to the enclosure (I realized before etching and covered that area with tape). Anyway, first time I did a (partly) reverse etch. This one will be treated hard, so I use it as it is.

The PCB is my take on a tillman booster, ROG Condor Cab Sim, a ROG ruby amp, a MXR MicroAmp, and a mixer all in one. I will use it to practice with headphones, blend in backing tracks, slave-power other effects, blend two cell phones for small parties, record with cab sim, drive a 1x12" cabinet (actually gets quite loud!) etc. It will work with a battery as well. The footswitch can shut off one channel (e.g. if I blend in a metronome and want to mute it temporarily).

If you dig it, I still have sample PCBs and a build documentation available...

Nice build mate! 
I wanna build something similar for a friend of mine, but I'm going to use another Cab Sim circuit,  maybe the Marshall one. How does your combo sound?

The cab sim uses the values from the marshall circuit (Details: http://www.runoffgroove.com/condor.html).

It sounds well with headphones, I added an additional Hi-cut for less noise/hiss (cuts off high enough to not influence the guitar signal too much but prevent ear fatigue). Switching the Cab-Sim on and off produces a clicking noise (only once, so I can live with that). It can be loud on a cab, at very high settings (beyond living room level) it gets noisy / oscillates. It is perfect for the use cases I intended it for.

Dude you can totally fix that with some JB Weld I'm sure of it. That stuff is strong as hell.

Never heard of that - cool, I will try that, thanks!

my vacation setup: Zendrive into HOF reverb into Leo Cab Sim Amp into Headphone. Blended with a great youtube backing track (Robben Ford "Help the Poor"). I used to use positive grid, but this is way better (especially with youtube backing tracks, which was never possible with positive grid).

I'm so glad this project is back on. I was worried it had disappeared in the Great Forum Crash.

The guitar is a partscaster: Sunburst Strat body with humbucker tele bridge, the creamery wide range humbucker, tonerider tele neck single coil, 5-way switch with Jerry-Donahue half-out-of-phase wiring, tele one piece maple neck.
It went through various iterations, with the current wiring (http://www.tdpri.com/forum/tele-technical/509479-fat-telecaster-wiring.html#post5988315) it is perfect for me.

The HOF looks a bit too much standard in this picture, I agree ;-)
