Sitting in front of my board right now, having a rejig to compensate for one less guitarist. I have 3 overdrives and one is two channel. You can have my ODB3 for £30 if you want, its a good starting point, lots of adjustable on it. The Sansamp bass driver is something thats kinda expensive, but it will last you, can dirt up amps with it, or just use it as a DI, which is gonna be fairly familiar to any sound man, so they'll know to work with it.
