Recorded an album aaaages ago on a 5150 with a 4x12 with a kick grille and it sounded amazing.
I've got a couple of tube screamers, usually I use both at the same time for more gain on the bass.
I'm gonna make a 2x12 kick grille cab to run under my lc30 for a bit more punch.
As for pedals, ts808 tube screamer, ts9 tube screamer, dd7 delay pedal, fender spring reverb pedal, ernie ball volume pedal and some old vibrato pedal I found in Denmark street for £15.
