Super versatile overdrive.
I had never even heard of the Ibanez Mostortion before finding out about it here on the Aion website. This is now one of my all time favorite dirt boxes. It is like a Tube Screamer but with a wider gain range and far more flexible control over the tone thanks to the 3 band tone stack. If you want boosted or scooped mids, this pedal does it with ease. Great for adding more treble bite to a darker sounding rig or taming peaky high frequencies.
A must build!
I was happy to find a CA3260 on ebay for a reasonable price, so I got it for this pedal. The build went fairly smoothly, although the smaller pots presented a bit of a challenge.
I usually mount the pots and then carefully slide the PCB onto them and solder in place.
With this build I was having an extremely hard time getting all 15 leads to line up at the same time, so I resorted to unmounting all the pots, placing them in their respective places on the PBC then putting the whole assembly into the enclosure holes before soldering…..it was tricky.
The other thing I learned on this build was to solder leads to the PCB “outs”, then solder those leads to the micro 3PDT bypass PCB, and THEN solder the micro 3PDT bypass to the 3PDT switch. I had been soldering the PCB to the switch first and then try to get all my wires in the right holes and solder…..was ugly…..it went much smoother this time.
I included a pic of the 3PDT PCB wired up before I soldered it to the switch.
I used a T-shirt hear transfer for the graphics….it took 3 tries….and still is just OK.
The pedal sounds great.

I did use the 10K resistor as the minimum-drive resistor. And I always use the 2M2 resistor in the RPD position.
