From the vendor
Is our take on the now discontinued EQD Speaker Cranker – A great simple build that supplies a low gain OD in a small footprint, low component beginner build. You can build this in a 1590A with one pot – or build it in a bigger enclosure with off board mounted pots and include the volume pot – this addition is super useful if you’re playing in your bedroom and not at Wembley!
Controls:
• Gain
• Volume (optional)
Note: Remember to socket your transistor.
