You will need to listen on headphones or half decent speakers to hear properly.
A new pre-built mod kit for the Monotribe, this adds 4 switches to change the drum sounds, decay for BD, tone for snare, decay for snare noise, decay for hi hat. The switches have 3 positions, when set to centre the default sounds are heard, when up or down the mod sounds are heard.
To install it you need to drill 6 holes and solder 5 wires, the circuit board and switches are pre-built.
I also do midi mods for the Monotribe, and I have some other mod kits coming soon so stay tuned.
Send me a message if you are interested. Pricing is reasonable but not as cheap as DIY as it has to be worth my while. There are lots of good DIY resources for mods if you google for them.
