well, if it sounds good... i'd live with it. changing anything would probably screw up the sound!

Yep. If it sounds good, then messing with stuff will probably only ruin that. Amps just have a certain mojo sometimes.
#5
Amp looks legit, I haven't had good experiences with most newer Fenders but the '59 Bassman is one of the best sounding amps ever made, if not the best.

^ depends if it's new or vintage.


If it's brand new I'd send it in to get fixed for sure.


If it's vintage I'd have it looked at by a tech but if it's not an obvious problem I'd just live with it for the time being.

the volume problem has to deal with weather you have a linear or audio taper pot. From the graph below you can see the difference the perceived volume is by following the lines on the graph.

So I'm guessing your amp has an Audio tapered pot. If you was to switch to a Linear taper of the same value the volume would increase more balanced as you turned up the volume.

My Mesa had the same problem very little volume till about 9 O'clock than it just peeled your face off.

If you start a reply with: I have never played one but I have heard good things about it! Your opinion is invalid.

do ya think they would toss such a pot in there to give it a quirky vintage mojo feel? or are the audio ones just cheaper lol. it doesnt really bother me, i had a blues deluxe that was similar but for that one it was volume on 2 it was on and loud, below that it was silent. i got this for gigging so im not looking for low volume play just was trying to find out if anyone else has quirky amps that like to either be ON! or silent.

They throw in a linear one to trick noobs into thinking there's more volume on tap than there really is. Not audio pots, which are "correct" for volume control use. Audio pots are logarithmic, just like human hearing. But the linear volume pot is an old trick like I said.

I couldn't explain why they do it. I know Mesa does the same thing. Someone more knowledgeable may have an answer for you though. I do know that because of those pots on my Mesa once the amp was turned up about half way. You seemed to be at max volume.

fender does it because they like to maximize their amps for the guitar center purchaser.
people crank them up to 3 and go omigod it's so loud i love. True story with the hot rod deluxe.

the problem is two things. the RI '59 bassman has a linear taper pot. and the pot value is 1M. with a 1M pot, the impedance coming out of the previous stage is rather low, it acts more like an on/off switch (even with an audio taper pot). it doesn't have any damage to the sound, it's just the usefulness. if you decide to switch it with another, i'd put in a 250k audio pot.

well i said 3 was loud, well 5 is clean with just some slight breakup but 5 was definately the loudest...honestly i dont see it ever going to 5 in a normal band setting, with my blues deluxe i had at one point, 3 volume wise kept up with a drummer and really messed up stage volume in a church band lol.

i know they dont keep going in volume that high on the knob, think the twin reverbs can pull that off, i love the amp though, i'll deal with the weird quirks.

That would mean more grid leak on V2a though. I'd split the difference and try a 500KA pot. Try to get a CTS one.

I'm not sure about the Bassman RI but the DeVille I had used this funky harness to attach the pots. You'd have to make another to fit any new pots should you go that route.

A funky harness you say? Is that a harness for a funky gibbon?
obscure Goodies reference

You can't just replace it in the harness? The pot, not the gibbon.

I never bothered with it. It didn't matter much to me. But from what I read on that site that used to be up about the Hot Rod series, the harness and the pot were inseparable.

That's not a difference in perceived volume thats how the resistance increases as you turn the pot. That does not directly correlate to how much volume the amp is pumping out or how loud the amp is to our ears.

But our ears do work logarithmically so it does equate. We use log pots on volume controls for a reason.
