Re: Non-modeling solid-state amps - is there such a thing?

When I was selling musical equipment, nothing had anything more than reverb and vibrato. Then Mesa Boogie showed how to use a master volume (not quite that simple but). Most everything had gain and a master volume and that kept the people in the front row from bleeding too much. There are a few amps...

Re: Gizmo for testing pot and cap values

John,

Thanks for the in depth tour. That is a very elegant way to compare the controls.

Now I really like this gizmo.

Re: Gizmo for testing pot and cap values

I like gizmos like this. Thanks for sharing. 1) If I understand correctly, the pots (250 or 500) are actuated by the same shaft. So you could not have a 500k volume all the way up with a 500k tone all the way down. 2) What might be useful is a way of removing the volume and/or tone control out of th...

Re: Cap size for bass

I'm a bit more monolithic. I like .02mfd for guitar and .05mfd for bass (passive pick ups). The tolerance for these parts is such that anything near those values works (for me). If you start to lose the high string with the tone control all the way off, then reduce the value of the cap.

Re: Recreation of 1900's Gibson O archtop

First off: Wow. Chris, that is quite a piece of work. Second: My interest was piqued by Randolph's mention of those Chinese guitars. The mandolin style guitars that I saw are obviously inspired (my word) by Monteleone. Intellectual property issues aside, you have to give those Chinese guitar makers ...

Re: Ideas for things to do with extra mini-switches?

How about: 1) Replace the 5 way with a 3 way and wire the outside pick-ups to it, like a telecaster 2) Mini #1 sends the middle pick up to the output so you have all combination of the 3 (in parallel) 3) Mini #2 is a phase switch for the middle pick-up 4) Mini #3 is the universal coil cutter That be...

Re: Pickguard adhesive

The transfer adhesive is a good way and the industry standard (though being industry standard is not, in itself, proof of infallibility). A pick guard so installed is removable by judicious moderate heat and naptha. I've had to reaffix several pick guards where the transfer adhesive has given up on ...

Re: using two Piezo strips in a hollow nonadjustable bridge?

The K&K Definity works very nicely with a floating bridge. They recommend a preamp but it had plenty of tone output by itself.

Re: 5 tones on a Tele? Not sure if this is a dumb question

My choice would be tele style pick ups, one being reverse wound reverse phase for humbucking when used together. I've wired Teles with 5 way super switches. The effect was 1) bridge and neck Parallel/out of phase, 2) bridge, 3) bridge and neck in phase, 4) neck, 5) Bridge and neck in series. While t...

Re: ES 137 style centerblock construction details

http://www.es-335.net/index.html There are informative (and drool worthy) pictures at this site. The first 335s were very solid and were wired through the F holes.

Re: Arch Top Mando Cello conversion

Unless you've already drilled the holes, I would suggest using guitar machines rather than mandolin machines. You might even need to drill out a guitar machine to accept that low "C".

Re: Squier VM Jaguar bridge swap

Brian and I are both guilty of assuming we know what kind of bridge is on the guitar. it is not the typical Jazzmaster/jaguar/mustang bridge we all know and avoid. From what I can see, the bridge in place is pretty simple and stable. The tuning problems are probably due to the short scale length. Th...

OK so now I n=know it doesn't have a tremolo. oops.

Try the heavier strings, be sure they are installed properly (safety posts) and pull them to brea them in.

Re: squier VM jaguar bridge swap

What kind of spring mechanism doe this use? It probably would be easier to block it from moving that to replace it. It would certainly be cheaper. That being said, if this has the typical Jaguar 24" scale, it will not be as stable as, say, a Stratocaster with a block tremolo. Going up a gauge in str...

Re: Any experience with the Guild George Barnes Acousti-lectric

Hans Moust is the Guild Maven. He might know what is going on inside the George Barnes. You should pick up Hans' "The Guild Guitar Book". Lotsa nice pictures of Guilds you've never seen. There is a guitar built for George Benson with a D shaped sound hole. Its original pick up was "bar mounted".

I misunderstood the topic being discussed. I thought we were going to be wistful about the 60s and 70s...

Re: Jazz bass pickup spacing

I have an 1980 article by Seymour Duncan which gives the distance from the nut to the pole pieces (jazz bass) as 27 7/8" and 31 9/16". This looks like the original spacing. My own opinion, worth everything you've paid for it, is that I prefer the old basses for just about any and all reasons. If I w...

Re: Can someone walk me through speaker design? I have no idea.

That kit looks like a lot of fun. Needless to say you are overqualified in regard to the necessary "woodworking". I got a pair of tweeters from them and they really revived our old beloved Baby Advents. I'll bet that kit will sound really good, and then the "I wonder if I....." will begin
