Apparently the Gotoh GB528 ultra light tuners can be dropped into the U5 with no additional drilling according to this video. This would probably help with the neck dive.

Are you happy with the output volume??View attachment 5067235 My U5 sounds really crisp, with good lows.
Well, the P pickup is louder than the bridge pickup. I must have the gain cranked on my Rootmaster 500 .Are you happy with the output volume??
Compared to my other short scale, the U5 pickups are weak, IMOHO.
Mine is the opposite, bridge louder than P.Well, the P pickup is louder than the bridge pickup. I must have the gain cranked on my Rootmaster 500 .
I'm suspecting wiring since mine is a lefty. If you wire right handed pots lefty, non-linier pots sometimes act weird. I plan on re-wiring mine righty (pots will work in reverse) to see if this is the case.QC must have been sleeping, when they wound these pickups.![]()
Having my tech look at this response.I'm suspecting wiring since mine is a lefty. If you wire right handed pots lefty, non-linier pots sometimes act weird. I plan on re-wiring mine righty (pots will work in reverse) to see if this is the case.

Is your's a lefty? If so, I bet you will note that the tone pot operates almost as an on/off switch. This is a classic sign they wired a normal righty pot to work lefty. They aren't alone, many manufacturers have done this in the past.Having my tech look at this response.
Thanks again Lug,
It sucks that I haven't been playing her lately, because of this issue with output issues.![]()

If yours is a righty, most of what I said shouldn't apply. Those problems come from trying to wire a normal pot to act like a true lefty pot. The weird thing is my bridge pup is wonderful, one of my favs I've ever heard. My worst case is just throwing in a Quarter pounder for about $100. The P pup IS useable, just not balanced the way I want.Not a lefty Lug,
I'm going to check out that tone knob thing next.
I can't stand the fact, I'll have to put in $200 for pickups, and electronics..
The rest of the build is top notch though.
Definitely not these pickups or electronics.
I'll have over $800 invested, when all is completed , if I don't sell her,and cut my losses.
This crap is making me sing the blues..![]()

So, I have GHS Pressurewounds on my Sire U5. I like these strings which are on my other Short Scale. I'm thinking of switching to flats for the Sire. I wanted to know what some of you prefer, flats or roundwounds for your Sire U5.
I have a set of StringJoys on my U5 right now. I have a set of pressure wounds I have been considering swapping. I love the LB DTFs on my G2220(modified) and my AGB200. I really like the feel of flats. But I would like to have one bass that has a bit more zing, so have been keeping the U5 with round wounds for now. Do the pressure wounds sound more like rounds? but feel more like flats? I would love that.So, I have GHS Pressurewounds on my Sire U5. I like these strings which are on my other Short Scale.

The Pressurewounds are in the middle of rounds and flats. They feel like a smooth round wound but have qualities of both. There's a whole thread on them that I'll put here. I have them top mounted but I'm having it switched to stringing thru the body because the silk ran out on A string.I have a set of StringJoys on my U5 right now.
