Hi guys, I have a newbie question: I am planning my first tube amp build, and I have been studying Robrob's site for a while. I would like to build a micro 5f1. I also play bass sometimes, so I was thinking of modding the original plan so I could use it also for bass. I have searched on the forum and I know that it may have a low volume, but it will be literally a bedroom amp. I am sure that it will be fine for guitar, but I have some doubts about bass. I found on the internet some caps values for the V1A bypass cap (from 25uF to 2uF or 1uF) and for the coupling cap (from .022uF to .01uF, or even 500pF) that could be good when playing bass. I would put these caps on a switch so I could have the "original" values and also these ones with simply a switch. The space inside the case won't be an issue because I will be building an head and it will be built from scratch. I will start from a long fiberglass board so it won't be a problem to find some space for two extra caps. Honestly, is it a bad idea? I am sure that I will build a Micro 5F1, but I am not sure about this mod. I know about the risks of high voltages, and I am obsessed with safety (also because of my job). Lastly, I am sorry if my English is not so good, but I am not a native speaker.
