So, I bought a Gibson Goldtone online, an amp I also had years ago. This one has the same speaker, but different brand of tubes (It’s An el84 amp by the way), and has had a Mercury Magnetics OT put in. It has a good sound especially clean, but the overdrive doesn’t sound like how I remember. It sounds much more like a Tweed Deluxe kind of fuzzy/farty breakup versus more of a 18 watt Marshall type roar that I recall from my last one. what would be the first step to making it sound more Marshally versus Tweedy in the drive sound? Are the tubes the biggest culprit? If I throw a MIAB in front will it naturally take on the characteristic of the pedal?
