    TL072 18V single supply pickup buffer to 25K MN blend pot

    Hello all, I have come up with this: It is a 18V single supply (bottom left) dual magnetic pickup buffer, based on the TL072 op amp (one half of the chip shown here, for one pickup). Pickup is modeled very simply at the bottom. Since the buffer uses single supply, we need to generate a...

    Fender Rumble 15 distorting with Aff. PJ

    Hello all, I recently purchased a Squier Affinity PJ plus Fender Rumble 15 set from a young grasshopper who apparently decided bass is not for him. The bass is fantastic, for the money or irrespective of money. The wee amp however, not so much. The problem is that I get distortion, especially...

    Help me identify these

    Hello all, I recently took these out of a bass I bought used: The are a short/long pair of SD Js, from back when the BassLines series was made. They are passive and have four conductor wiring which I think is a bit unusual for a J pickup. Neck wired in series has a 11.5KOhm DC resistance...

    250KΩ linear pot with a center detent

    Hello all, what the title says. I'm looking for center detent on a linear pot with a value that is not exactly easy to find with a center detent. Where can I source such a part (I'm based in Europe). And if I can't, do you know of a quality pot that is not very hard to acquire that when...

    Do you recognize this (perhaps EMG) pot?

    Hello all, I recently bought a used P/J EMG pickup set, and the seller was kind enough to include what seems to be an active potentiometer of some kind. I think it looks dated, not something from their current line of products. There's no center detent on it. Do you guys recognize this by any...

    Type of wood on a solid finish bass body

    Hello, I got the chance to get, from a good friend, an obscure far east made 30" short scale bass. I would date it at around late 80s, early 90s. It packs a pretty good tone on it, although with some of what I consider shortcomings of the very small scale. My intention from the start was to...

    Dual coil switching galore on a bass made in 1990

    Hello TBers, allow me to first give you some brief context: Since a few days ago, I am the happy owner of this nice neck through bass, made in South Korea by Cort in 1990: It has a preamp with discrete parts on a PCB, and to my surprise, the pickups are not passive humbuckers but active ones...

    Peavey Headliner 112 specs mystery

    Hello guys and gals, and happy new year to all! I 've pretty much decided to purchase a Peavey Headliner 112 cab. I understand this product is discontinued in the US but apparently there are still a few pieces still in stock in shops around Europe where I live. I always take a careful look at...

    Fretless fingerboard string marks correction

    Hello TBers, a fretless has fell into my hands, it's a beautiful Warwick five string. But it has been played a bit (perhaps using rounds) and there's some specific spots where it buzzes too much, like rattling. Most characteristically at A string 7th fret (E) and D string 7th fret (A) for...

    Barrel type jack installation tool

    Hello TBers, as most of you know, replacing a barrel type output jack can be a PITA because it needs to be tightened of course, and usually a normal wrench has trouble reaching its nut. Are you aware of a specific tool for this job? Something like an angled wrench that can do it? Any links...

    Mini amp from class D head + mini stereo speakers

    Hello TBers, I recently replaced my stereo speakers with a nice pair of Magnats. So I am left with a couple of 90s AKAI 3-way speakers, rated at 50w and 6Ohm each. I was wondering how I could make good use of them, and since I sold my last amp due to severe neighbourhood problems, I was...

    Alternative to Thomastik-Infeld Jazz flatwounds

    Hello all, I 've been playing Thomastik-Infeld Jazz flatwounds on my six string (.33, .43, .56, .70, .100, .136). They have a steel core and a nickel alloy winding, and sound absolutely fantastic. But lately I 'm into downtuning my bass, half step, or even full step. So the string starts losing...

    Wiring ideas for two 4-conductor humbuckers

    I am starting this thread in order to not derail another one: Insertion Loss? My situation is that I have an Ibanez SR605 and a pair of Nordstrand Dual Coil pickups. I was wondering about insertion loss and if I should go active or passive. In the process I got the following response: This...

    Sanding Swamp Ash

    Hello TBers, I have this Warwick Corvette I wish to let go and before I do that I would like to bring it back to pristine condition. The main issue I want to correct is small scratches/dents on the swamp bash body as the neck is pretty much immaculate. A friend of mine has informed me that the...

    Properly sitting a bass on its back with a rest

    Hello forumers, inquiring for your sagely advice. My question is about making measurements on a neck, for example height of a string above a specific fret. But the question is more general as you will see. Question is, if I have to sit a bass on its back with a rest so that the headstock does...

    Puzzling electronics issue (grounding?)

    Hello people, I 've replaced the pickups electronics on a Brian Moore i5 bass I have and I am having a weird issue show up. I 've wired up more than a handful of basses in my life but it's the first time something like this occurs. So this is our specimen. I have installed to it a couple of...

    Even fretless fingerboard levelling tips

    Hello everybody, I have this nice medium scale (32") Warwick neck which I thought would be very cool as a fretless so I did the big leap and removed the frets. Removing the frets was a tough job as the wenge board is extremely hard. After removing the frets I placed some medium viscosity ca...

    Sanding pickup polepieces

    Hello, I recently acquired a set of open polepiece passive Js to replace my closed type actives, for 5 strings. The pickups work fine, only problem is, the polepieces are radiused, and the radius is less than the one on my bass' neck. Result is the A string sounds a bit louder than the...

    Using 2 Js as neck humbucker

    Hello ladies and gentlemen, I have a very nice Brian Moore bass that alas, has one noisy pickup. It is a humbucker and yes, it is noisy, I guess due to poor construction. Now, I am thinking about removing it from neck position and constructing a home brewed pickup from 2 EMG Select Js I have...

    Even sanding tips

    Hello, I have this nice bass body, alder back with a flamed maple top. It used to have a poly finish, which I have now stripped down to 150grit sandpaper. The basecoat from the poly finish was a good guide about when to stop sanding because of the colour change when the actual bare wood...

    Good candidate for stripping the finish?

    Hello ladies/gentlemen. I am planning on buying this used specimen: Invalid Link Removed However it is slightly beat up with dings and scratches all over. It is a maple neck through with maple wings and a nice red finish. I was hoping to sand all the red finish from it and make it natural...

    Hipshot A5 bridge spacer

    Hello, I am interested in getting one of these nice Hipshot bridges for my bass. Problem is the fingerboard on my bass is fairly high and I will most probably need a spacer under it to avoid setting the saddle pieces very high, thus causing a big breaking angle for the part of the string past...

    Identify this Ibanez

    Hello, calling out to Ibanez experts/historians. I have been offered a trade with this beat up Ibanez but I am considering it cause apparently it is a Prestige made in Japan in the year 1997. Can you identify the model, woods, electronics? Shouldn't it have a monorail bridge? I thought all...

    Passive pickups/preamp bypass

    Hello, I have this bass with passive pickups that are fed into a 250K blend pot and then into a 2-band preamp. The preamp's output goes on a 25k volume pot. I 've been thinking about the possibility of a push/pull volume pot for preamp bypass, but using 25k will be too low for passive pickups in...

    Making a solid nut base

    Hello, I am replacing the stock nut on my new Ibanez. The problem is the original was not seated very well (there was a gap under the treble side of the nut). So I am trying to sand the neck wood under the nut to make an even surface and at the same time take care to have a 90 degree angle with...

    Front Coil/Parallel HB/Rear Coil wiring

    Hello people, I have a set of Nordstrand Dual Coil pickups, with four conductors. They are currently wired with one 3-way (on-on-on) switch each, for Series HB/Single/Parallel HB mode. Is it possible to wire the switches for Front Coil/Parallel HB/Rear Coil instead? That's the preferred order...

    Fretless board levelling

    Hello, I have defretted a 4-string bass, using maple strips in the fret slots. It was a fairly clean job but there's one thing missing: Proper fingerboard levelling so that it has mwah all over. I have seen a video tutorial where a fingerboard is levelled using a long steel beam with sticky...

    0000 steel wool vs 1000 grit sandpaper

    Simple question: Which one makes for finer polishing 0000 steel wool or 1000 grit sandpaper? Does wet sanding with 1000 grit and lemon oil make sense for better results?

    Knobs for EMG preamp pots

    Ibanez SR705 vs SR505

    Hello guys, I am thinking about purchasing one of these two basses by Ibanez. My local dealer does not carry them at the moment so I can't try them out right now and would like your opinions/input. First of all, it seems Ibanez are using a new wood for their SR necks lately called Jatoba, the...

    Seymour Duncan ASB active soapbars

    Hello, I am thinking about replacing the passive MK1 humbuckers on my 5-string Cort neck through bass (very Ibanez like), to get a wider frequency response, a typically more modern tone. These SD soapbars are the only active pickups I have found with a Bartolini soapbar size (MK1/P2) and since I...

    Bartolini MK1 sized active soapbars?

    Hello, do you happen to know of any active pickups for these pickup dimensions? So far the only model I have found that is a direct replacement for MK1 (or P2/P4) is the Seymour Duncan ASB soapbars: http://www.seymourduncan.com/products/basslines/cutting-edge-1/asb5_asb6_activ/ I would...

    Digitally programmable - Analog Path

    Hello, I am not sure if this is the right place to post this thread, it is partially because the answer could be a multi-effect. I play in a cover band and we play really diverse stuff so I need easy access to presets for Drive, EQ, Volume, via foot switches. But I want an all analog signal...
