The SMP Tone Grenade uses a 12AU7 tube for a clean boost all the way up to a mild bluesy overdrive. This pedal will add that ‘tube tone’ to any solid state amp and gives additional rich harmonics. Nothing fattens up your sound like a Tone Grenade!
The SMP Tone Grenade runs off any 9 volt Boss style negative tip adapter. At Stunt Monkey Pedals, we recommend either the 9V Visual Sound One-Spot as it will provide plenty of clean power to this and many other pedals all from one small adapter or the VoodooLab 4×4 for the quality they produce and the kickass warranty on their products as well as the ability to switch to 12V for more headroom! You’ll get more volume but less gain when running at 12V. **Never exceed 12V as any more than this will severely impact tube life.**
You can use any 12AU7 tube (valve) in this pedal; replacements can be ordered from Stunt Monkey Pedals.
