Hello, guys. I have a Frontman 15G but it isn't the best amp you could imagine.. it has no reverb.. the guitar tone is a bit odd and the amp has lots of noise and thermal hiss. I have just opened the enclosure and I saw that the PCB has empty spaces with missing parts and it says 'for reverb models only' .. which makes me think that the PCB for the reverb model (15R) and the non reverb model (15G) is the same.. So maybe i could just add the missing parts.. but I can't find a schematic for the R-version.. could someone help me, please?
Another thing.. about the hiss - the solution is to lower the values of all resistors which comprise dividers and filters (for the filters if i lower the resistor's value n times, i have to raise the capacitor's value n times to keep the same RC constant and therefore frequency response), right? Do you think that all that can be done and is worth it?
