Kiwi Posted September 18, 2015 Posted September 18, 2015 After being dissatified for a while with the gain on my Burman Pro501, I decided to replace the remainder of the chinese valves left in by the previous owner (from Lindisfarne) with Sovtek 12AX7 LPS valves. All I can say is that it transformed the amp overdrive from a cheesy sounding 70's fuzz box with a flabby bottom end from a Dave Stewart track to a nasty, raw sounding monster with a tight bottom end and loads of crunch. If you want to bump the gain up in your amp, I can't recommend the Sovtek LPS valves enough.
gary mac Posted September 19, 2015 Posted September 19, 2015 Love that description of the original sound to the new improved version
Kiwi Posted September 19, 2015 Author Posted September 19, 2015 The difference is remarkable. It's become a completely different amp! I'll probably bring it to the SE Bass Bash...
