MT-2 Quad-Gain Plus Mod — Now for Guitar & Bass

WARNING! — The OPA2134PA opamp, of which are included in many of my kits, is currently extremely hard to find. Mouser and Digikey are currently out of stock with none expected until 2023. I have hundreds in stock. BE CAREFUL BUYING THE OPA2134PA ON EBAY. THE MAJORITY ARE FAKE! Manufacturers in China are rebranding cheaper opamps and selling them as OPA2134PA opamps. I test all my OPA2134PA opamps I buy. You can easily test whether a OPA2134PA has been rebranded. Do this, take some Acetone on a Q-tip and rub across the lettering of the opamp. If it is Fake the ink used to print the labeling will dissolve into the Q-tip.

This kit is a brand new mod for the MT-2. I have built it from scratch around the Quad-Gain switch assembly and the two new opamps! I have taken the pedal and flattened the EQ. That’s right, the original box of bees has been transformed into an awesome dirt box. The MT-2 has two gain stages with a ton of gain. By replacing two of the opamps I’ve reduced noise and added clarity. The two switches now offer 4 gain modes! That’s right, FOUR! A ton of tonal territory is now available, from singing Johnsonish type violin leeds to edgy crunch and all points in between.
