    Are my double-line Klusons really vintage?

    I have a lovely old partscaster that came to me with what appear to be vintage double-line Klusons. It was purchased around 1999 and sports a very early (first year?) Schecter neck and has no additional tuner mounting holes in the headstock. Everything checks out visually, but what gives me...

    More undesirable glitchiness

    What coding error is bringing us this nonsense? Recent software changes seem to be breaking things that didn't appear to need fixing.

    How do I delete my classified ad?

    Searched, but can't find an answer. I don't know how to mark the item as sold, either. Older instructions don't seem to apply.

    An observation: When all the components are in spec...

    Last year, I set out to make my 1964 Deluxe Reverb, which I've had since 2001 or so, as close to original factory spec as possible. I didn't touch any coupling caps, but I measured everything and replaced every capacitor and resistor that had drifted over the years, as well as reflowing a few...

    Did the background color just change?!

    ...or is just my imagination? It looks paler, more '58 than '52...

    Bigsbys: best practices and partial myth-busting

    I've been playing Teles and Gretsches with Bigsbys almost exclusively for about twenty years now. My guitars tend to stay in tune very well indeed; barring abrupt changes in temperature and humidity, most can easily stay in tune for an hour or two of heavy use, maybe with a quick touch-up or...

    The much-vaunted JJ E83CC (NOT ECC83) "frame grid" tube

    I ordered one to see what the fuss was about. Here's my capsule review, copied from a social media post, which explains the gratuitous curse words: "It's a lousy tone-shaper for V1 (first pre-amp stage) in a Fender amp; it seems to eat low mids and sh*t overtones, but fails to produce pleasing...

    1964 DR: Bigger filter caps or not? A trade-off of sorts...

    I'm really just thinking aloud here... I currently have the standard 16 uf filter caps, and I'm running a 5V4 as a rectifier (I have a bunch of old US-made 5V4s), so the rectifier's already seeing 2uf if over nominal spec, which seems fine. I have new 22uf caps (for the first two positions) and...

    Quick question about bias and tube types (BFDR content)

    I decided to roll some power tubes in my BF Deluxe Reverb. Naturally, I got very different bias current readings on each tube. I ended up replacing my JJ 6V6S tubes with some old Jan Sylvanias. I know that bias current and plate voltage are interdependent, but why would the Sylvanias give a...

    1964 AB763 DR filter cap question

    I recapped my old BFDR some time ago and screwed up. It seemed to work just fine, but there was a lot of reverb noise at low volumes, so I only used it for loud shows or just kept the reverb down when playing at home. (I did a mod that increased the wet/dry mix by 130%, so it was pretty wet...

    4-way switch with Bardens: weird issue resolves itself

    Connecting the bare wire of the neck pickup to ground killed the signal. So did making contact between the neck pickup's rails and the strings. I took out the neck pickup, looked at it, cleaned it, checked continuity, and could see nothing wrong. I put it back and everything functioned normally...

    Oh yes I did! Dakota Red refin, 1968-69 body w/previous refins

    I posted about this guitar last year when I was restoring what I thought was the original finish, an opaque blond believed to be aged Olympic White. Along the way, I found that the guitar had originally been translucent Blond, then two shades of blue (one apparently LPB), and then the opaque...

    DRRI bias question: Fender says 37V DC @ TP (Test Point) 36, but...

    ... everyone here says this tells you exactly nothing about actual bias current. I'm very comfortable measuring bias current with the shunt method on a PTP DR, but the RI doesn't really provide easy access for the same method, and I don't have a bias probe. I know, they're cheap and I should...

    How shocked was I? A cautionary tale and a question...

    I've been working inside of amps for a while, well aware of the dangerous voltages therein, but I got a pretty hard "bite" recently when exploring the upper and lower ranges of acceptable bias voltages in my original '64 BFDR. I had just measured the plate voltage at 400V with 116V AC at the...

    Botched Bigsby install on post-2012 52RI (NYC Craiglist)

    Here's the ad: https://newyork.craigslist.org/mnh/msg/d/fender-telecaster-52-reissue/6628413179.html Can't decide if I should send this message to the seller: That's the worst Bigsby installation I've ever seen. If it had been done properly, it would enhance the value for some prospective...

    Bigsby bridge surprise! I like the original best.

    Just thought I'd share the surprising fact that I preferred the notorious JM/Jaguar bridge to a Mustang bridge, a StayTrem, and a Mastery on my "mixed sixties" ('66 neck, '69 body) Tele with a B5 and 2002 Barden pickups. The StayTrem needs more distance behind it to work properly. The Mustang's...

    Late sixties paint and body questions

    Way back in 1986 I bought a heavily modded 1966 Tele for $450. Some clown had installed a Kahler vibrato and a Duncan JB in the bridge position. It was the standard banana-pudding opaque blond, and I had no reason to question its authenticity; the neck date was clear and matched the serial...

    Redplating and ridiculously low voltages (BFDR)?

    A few weeks ago, I opened up my original AB763 DR to trace some noise. It turned out to be a dirty standby switch, but I checked all resistor values and solder joints, re-tensioned the tube sockets , and fine-tuned the bias while I was in there. I hadn't used it for a while until last night; it...

    Reverb tank output impedance: 2250 Vs. 2575

    I'm thinking of replacing a short-decay tank in an Ashdown Peacemaker with a medium-decay. The existing tank is 800 Ohms in, 2250 out. I'd have to special-order one with identical specs to get a medium-decay, but MOD makes one with the same input impedance and a 2575 Ohm output impedance. This...

    More messing around with BFDR reverb circuit

    So I tried altering the value of the resistor that dumps the dry signal to ground; I increased it to AA763 specs (4.7M), didn't like it, and compromised at about 4.2M. All well and good, but I didn't like the idea of altering wet-to-dry ratio by reducing the dry signal. I decided to try...

    Follow-up: tweaking the AB763 reverb to AA763 specs?

    Months ago, I asked about increasing the value of the 3.3M resistor on the reverb circuit in my BFDR to 4.7M, which was the value in the short-lived AA763 circuit. I play a lot of surf, and there's no such thing as too much reverb, as far as I'm concerned. At least that's what I thought! I...

    Curious relationship between wall voltage and plate voltage

    As I learn more about biasing, I'm trying to come up with a formula that will allow me to calculate plate voltage based on wall voltage so that I can bias my amp within a range that will allow safe and predictable operation across a range of wall voltages. My own wall voltage varies a lot, so I...

    Disappointing voltage regulator

    I bought a Tripp-Lite voltage regular — a used older model, so it was cheap — and was disappointed in its performance. It only kicks in to boost voltage when the wall voltage hits 110. I thought it might be defective, but I called the company, and even their latest models don't start to...

    Played the new Vibrolux w/Bassman tone-stack channel

    I saw one of these at Guitar Center and gave it a spin. The "Custom" channel sounded fantastic. Apparently, it has a "Bassman tone-stack," but they don't specify which one. The classic tweed circuit, perhaps, but without the benefit of the interactive volume controls, 5Y3 rectifier, and other...

    Bias control won't go down far enough! What to do?

    This is a follow-up to my post earlier this week about my '64 DR. In spite of being happy with the sound, I decided it was time to learn how to bias with a multi-meter, and I started out just taking some readings. Plate voltage with the 5V4 rectifier was startlingly low. I have two, and both...
