If you ask this question in Google you will open up quite a few discussions or pointers about this. It was once followed as a ‘general’ rule as having 500k pots for humbuckers but Delano has 250k pots for all their pickup schematics. Go by the pickup manufacturers recommendations….using 250 or 500k pots can affect treble or even volume, including which value capacitor is recommended.

Thanks and yes, I’m not looking forward to even pulling the main board out as it appears to be all one lump of connections. I must say ‘we are not amused’ by Ibanez’s wiring!

I may have missed something here but…….Dual channel or stereo amplifier? A dual channel runs as mixing two inputs into a mono output signal whether using (one 8 ohm)or both speaker (16th ohms) outs to your two cabs…. A stereo amp will allow two separate load outputs for two separate speakers….8 ohm load per cab.

I’m not getting any response from the mid control on this bass, either boost or cut but the bass and treble work okay. A new battery was installed. Taking off the cover plate revealed more wiring than I’ve ever seen in any bass and I’ve wired a few active circuits over the years. When I pressed down on the wiring the signal was interrupted but before ‘getting in there’ I’m wondering if anyone has had similar problems that they’ve been able to rectify. I’ve messaged Ibanez/ Headstock U.K. but no response yet. Thanks.

I’ll come back in on this conversation with this……many years ago when I played for Marshall Amplification at the giant Frankfurt Music show, I happened across Mike Tobias’s stand. As a budding luthier myself, I was very keen to chat with one of America’s top bass builders at that time, ( the great bassist Jimmy Haslip, the upside down left hand six string player from the Yellowjackets used Tobias basses). Mike brought a bass out for me to try as we were discussing different woods but that bass wasn’t the sound I looked for so he brought another two or three basses out but the last bass was ‘the’ sound that pleased me most. It had a main ash body, with a cap of walnut I think. I had started building using ash already, liking the sound very much for my style of fretless finger playing. Yes, wood does make a difference, though not the huge amounts we may imagine by reading descriptions like..’provides punch and clarity…cuts through the mix’ etc etc. a lot of this is done by fingers or pick style and aggression, strings, amplification. I am happy to say that both audience and bass players attending my gigs always say they hear my bass notes really clearly and mixed in well with whichever band I’m with, then go on to complain that most of the time with other bands, the bass is very woolly!

Barrell Jacks are literally a barrell length that encloses all of the Jack plug. Type in barrell jack to Google and pics will come up. Commonly used for instruments with active electronics to ‘un switch’ the battery when not in use…..or in instruments where the instrument cable jack plug is inserted on the edge of the instrument. Fender type instruments usually use the ‘normal’ jack.

Edited……. Apologies but I was trying to Tru Oil! I use Tru Oil (Birchwood and Casey). Perhaps you were warned off from using oil after staining if the stain was water based? Also, using 'Micro Mesh' as a final finisher before oiling and between coats really can bring up an oil finish.

Stop suggesting..!

Yes, a good deal to have ...except I mistakenly ordered the medium scale ones and you can't send these 'free' ones back doh!

Well, could be a string that wasn't quite ground to normal diameter or has a miniscule kink right 'there'..... could be if the pickups are... a) too close to the string when you depress at 14th fret or above... b) very strong magnets pulling the string/dampening it.

Possibly a lone fret slightly high, possibly a shim under/ in the neck slot has raised the neck height, possibly the strings are set really low and play fine in lower positions……difficult to tell without handling the bass myself.

…….and with a fretless the dots are large enough to help intonation placement of wandering fingers! Cheers.

You’ve broken the rule 😆 but I have to say the side dots are always too small as on my Fender Roscoe Beck, they appear to disappear on stage, hence when I build basses, it’s 3mm black dots on the maple neck wood

Apologies for the late reply bpc…….The bass is passive but I have actually dropped in some new pickups now and a new pot, seems to be okay on the one gig tried so far. Thanks.

I've been using these straps for over twenty five years and more and still in use, with a couple of recent new thick leather ones for me and two for a guitarist friend. Mark at Stones Music started this business up in the 80's after being a luthier and working in London (Rokas) so he is well versed in the music business and a very nice person to deal with, pay the money and get the quality.. https://sites.google.com/site/stonesmusicgbbo00/stones_straps

There’s two sides to every story! Enough people have hired Gomez over the years and having seen him play I’m not surprised his double bass playing was sought after.

I think getting a luthiers repair shop to just look at it may yield a conclusive result. When you had light strings on, the neck had some ‘backbow’, when heavier strings where on it was the opposite….? That’s quite dramatic movement really and a first thought was obviously the rod isn’t doing its job but maybe just maybe it’s actually broken internally and although it isn’t rattling (but go ahead and give the back of the neck a good hand palm slap and listen) adjustment will be of little use. I had a new Fender years ago where the neck would not be straight. I couldn’t adjust it enough and I was on tour! I replaced it with a replacement neck and put the old one on a shelf for 8 years. After time I checked it and it appeared to be good so I took off the fingerboard and put a Macassar ebony fretless one on and it’s been fine. I concluded that it had not been correctly prepared/dried before assembly. Good luck.

Opened the amp. no sign of anything burning out, loose or dusty, connections all appear secure...

I'm running into a Markbass 2x12" Ninja cab and not using anything like 'loud' input/output' ie input 4 output 3 so it shouldn't be heat causing the problem and it doesn't feel over hot at gigs end. I would think any thermal issue would have the auto cut out switching in, I've had that many years ago on a different amp. The actual change appears to be more tonal lower end bringing volume with it....

Thanks people……I might open up the box and check everything is secure inside.

…..haunted in the best possible way 😄

Without naming the amp to prevent any pros and cons for it…..but I’m aware that it seems to get louder by itself about halfway through a gig. Is it possible for a ( non valve ) amp to do that as I’ve never had this before either in this make of amp or earlier makes? I’m looking at other possible sources as in pedal board, pots, cables but if any knowledgeable folk know more than me, please advise.
