Your right I have noticed that about the BC30 and the So Cal. Also the BC30 has a tube rectifier and the So cal has solid state. If you look at the chassis for each, I reckon the So Cal is the BC30 chassis inverted. Cost effctive I guess.

The resistor swaps and C15 mod will only affect the overdrive channel. The other cap removals affect both channels from memory.

G'day, I have finally completed all the mods on my BC30 as follows: C3,C5,C6 removed, R15 - 1.6K, R21- 1.1K and finally C15 reduced from 22uf to 2.2uf. The things now sounds great. EQ is extremely effective and sensitive. Sounds very different to when I got it, has more gain but it is by no means a 'high gain' amp. Bigger sound and more responsive to touch. I am finished now and don't intend to tinker anymore but you never know.............

G'day, I have tried one further change which is to change R21 from 2.2k to 1k. Result is more gain and slightly fuller tone in my amp. Suggest using alligator clips a A-B test it. My next experiment will be to reduce C15 to 5uf or some value less. Problem is that to do that properly the PCB needs to be removed which will be a dog cause all the VR's are directly attached. Current config is C3,C5,C6 removed R15 now 1.6k and R21 now 1k Cheers Greg

Hi all, Thanks for this thread. I have used the suggestions to improve my own BC30. I play a strat with Fat 50s PUPs and found the clean channel insanely bright. I have done the following: removed C5 C6 and C3. I have also exchange R15 for a 1.6K. I did try removing C10 but found I lost way too much top end from channel two and replaced it. Before exchanging R15 My amp had a real 'snotty' midrange which was driving me crazy. It now sounds great. I would like to a slightly more fuller rounder sound though, any ideas? It is a much nicer sound now and very useable but I wonder if there is more sweet stuff to be had. The clean channel now is beautiful and I won't tinker with it anymore at this stage. Cheers Greg
