Reconciliation (Trainwreck Express clone part 3)
The more I think about it, the more it bothers me that I’m calling this amp a ‘clone’ of a Trainwreck Express. I guess a very significant and distinguishing aspect for the community regarding what those Trainwreck amps are all about is not just the circuit itself (especially since there are so many different versions… Continue reading

What have I done? (Trainwreck Express clone part 2)
At some point in 2020/21, I must have thought that it would be a great idea to build a high-gain amp without a master volume, or perhaps make it more versatile with a simple two-wire post phase inverter volume control. Turns out I was very wrong. I wired everything up for a first test, and… Continue reading

Old/new guitar amp project (Trainwreck Express clone part 1)
Here’s another project that’s been in the pipeline since the end of 2020. Back then, I designed a PCB for a Trainwreck Express-inspired amp. As far as I remember, I thought it would be an interesting idea to fuse this classic, mythical amp with a modern design and layout of my own, and see/hear where… Continue reading

Mordpol X2 Guitar Poweramp
Update 14.04.2020: Something unexpected happened – I wasn’t happy with the PWM fan noise, so I opened it up again, messed around with some botch wires and changed the programming. The PWM frequency is now at around 125kHz, absolutely inaudible to my non-bat-ears. No hum, no PWM noise, no tears. Update 03-2020: There’s been some… Continue reading

Mordpol X1 4-Channel Guitar Preamp
I started this project back in 2006/2007 and until a couple of months ago the PCB for it was lying in a box in my cellar. At some point I was looking for something and found it and thought I could maybe give this project another go after forgetting about it for 12 years. So… Continue reading

Mordpol DK100 Guitar Tube Amplifier
These days I’m working on a 100 Watts tube guitar head – featuring four KT77 power tubes and three 12AX7 in the preamp. It’s a two channel amp – one channel clean (Fender-like) – one channel crunch/lead (think hot-rodded Marshall 2203) and there’s another feature to combine those two channels, meaning to put the clean… Continue reading

Mordpol Ag47 Guitar Amp (Marshall Silver Jubilee Clone)
Update 18.05.15 The amp is finished!! It sounds quite a bit better than the prototype already. I’ll post some pics of the 2×12 combo enclosure loaded with G12M Creambacks in the near future + the layout will be available here too. I left some self-explanatory pictures here. The prototype of this amp can be heard… Continue reading
