I use the Para Driver, it’s the one but of kit that whilst I obviously could live without it, it would really really upset my day and my sound if anything happened to it. I’ve had numerous preamp/DI pedals (Aguilar Tonehammer, Sansamp Bass Driver, VTDI, Behringer BDI21, MXR M80) and the trusty Para Driver for me is the king of them all.
