Fender Princeton – Not the Princeton reverb, but the smaller amps based on two 6V6 tubes. These are too tame for many guitar players and can still be had for under 0. Gibson GA-40 from the mid 1950’s – This is a killer amp. It had a 4×10 speaker configuration and minimalist circuitry. I have been told this is the best alternative to a ’59 Bassman that you can get and the heads go for about .
If you have to cut it with guitar players, your best bet is to get something with 2 12-inch speakers or 4 10-inch speakers and 2 6L6 tubes. I found the one I played through to be too sensitive and got a lot of feedback, but everyone swears by them. The cabinets are very cool and you can slide the head into the back of the cabinet for transportation. These are great harp amps and readily available at affordable prices.
For those of you that are still confused or need to be hit over the head, here are my suggestions on what amps to consider.
The feedback/filter caps in the two gain stages varied from 500p F to 560p F, just like the real triangle Big Muffs.
These are Fender Tweed Deluxe style amps from the late 50’s and early 60’s.
They have usually two 6V6 tubes and a 5Y3 rectifier.
The circuit was basically a straight rip off of the Big Muff four stage transistor circuit, but some of the cap and resistor values were modified well outside the range E-H was using in Triangle Big Muffs from this period, giving it a slightly different tone than many of the real Triangle Big Muffs being made at the time.
To my ears, the sound rivals many of the Triangle Big Muffs I have played, with perhaps a bit more biting distortion sound.
