I can tell you I didn't do it without first hearing the Hi-Gain and gigging on it. I took my brand new 4003FL to one of the nicest jazz gigs I had been invited to for a long time and it did really well--lots of upright tone. However, the notes were just not as warm as I had hoped. I would say the tone was a bit sterile, especially in the upper part of the register. I had been compiling Toasters for just such an event and with iiipopes' help I had the second one installed in the bridge (I was kind've scared to do it myself). For a fretless, I feel like the double Toaster setup really adds to the sound--to the clarity and depth of the notes and to the fretless character. This is probably due to the broadened magnetic field. The sound is very, very smooth, silky, and professional sounding. It sounds like a true "boutique bass" to me now.walker wrote:A toaster in the bridge position! I've only seen that once before. How do you think it sounds compared to the standard high gain?
I would STRONGLY recommend this mod for fretless basses. For fretted, I have no idea what would result. I am 100% content with two Hi-Gains in my fretted 4003.
...That said, when I get my 4003 MG [fretted], I have two more Toasters and will try this...will report...
