I'm buying a new set of tubes for my amp and I'm going to order them from eurotubes.com. There a few options and I thought about buying the high gain set because I thought my amp lacks a bit of gain, but then I got an overdrive pedal and when I used it to boost the lead channel I got more than enough gain. So, now I'm not sure that the high gain set is the best choice for me and I even consider buying the most expensive gold pin set. What do you think about it, it is really worth that money and what is the better choice, I mostly play hard rock but when I play lead, I need much more gain than for rhythm.

Id probably go with the standard set, but you can always email them your question and see what they recommend.
