Details

Period-correct specs, warm tone. Genuine handmade tone caps, hand-picked by our friend Mitch Ingram at Emerson Custom Guitars and Electronics.

New old stock paper-in-oil caps from the former Soviet Union are prized by aficionados for their period-correct specs and subtle warm tone quality. Sold individually.

Capacitors are energy-storage devices that filter the high frequencies. A cap lets the tone control roll off the treble response, progressively warming the tone. The higher the value, the more bass output from the tone control at its "zero" setting.

A cap wired to a potentiometer creates a standard tone control, as explained in this article: How a tone control works

Hands Down The Best !

By Tracy G from Indianapolis,IN
(Customer's Reviews) Sunday, April 13, 2014


I have used every cap on the market in the last 30 years including true Bumblebees and these are by far the BEST!! Very rich warm tone I will be ordering more for each of my guitars.

My personal favorite

I love these caps. Tone, tone, tone, tone and did I mention tone? They work great with vintage output as well as modern high output pickups. With these caps your instrument tone control won't have a sweet "spot". It'll have about 20!

Unfreeknbelieveble.

I'm sitting here practicing and I had to stop just to give my review of these caps. At first I didn't notice a big difference but as I'm breaking them in, I am blown away by the tones I am getting. I took a Chinese 335 knock off (with a great neck and body) and swapped all of the electronics out and put in these caps along with new pups, pots, switches, jack, wiring, bridge, tailpiece and nut. All parts from StewMac. What a difference. Best sounding electric I've owned by FAR. I got their less expensive version pups but they don't sound like it. With these caps my dog looks at me when he hears the freakin growl. Get these, break them in and see for yourself. Thanks StewMac.

Fantastic

I suggest it all kind of players which who uses single coil pickups.It eliminates harsh sound. But price a little high.

Smooth

In my LP custom shop R9 with the addition of Joe Bonamassa pickups these caps are the icing on the cake...way to go StewMac

That Elusive Sound

By Jim A. from Illinois
(Customer's Reviews) Friday, November 22, 2013


I have an Ibanez Artcore that just didn't sound right - harsh, no definition, slightly muddy tone, very little articulation. So, when I couldn't stand it anymore, I dropped a pair of TV Jones Classics into it, and finished the refit with a pair of these caps. I also shielded the pots with the copper tape, available here. Talk about a night and day difference! Astounding! Now, as you roll back the tone controls, the sound gets creamy and smooth, no harshness, no mud! Yes, the pickups made a big difference, but these caps match up exremely well. Expensive, but worth it. Throw away your modern disc caps, put these in, you won't regret it.

Great!

The mid frequencies really smooth up. Sounds sweet. But it's an expensive stuff just to get the sound right. What can we do rather than buy it nayway? =D Great stuff.

Just Great Tone

By T Zero from Dallas
(Customer's Reviews) Monday, June 03, 2013


These are just great caps. Smooth and creamy all the way down without getting muffled and bottoming out. I'd put them right up there with original Sprague or high-end repros. I'd give them five stars, but I might need more and don't want you guys to buy them all.

TONE!

By Leo Matthew Chamberlain from USA

ok kiddies I will give you a couple secrets to Great Guitar TONE! First of all replace whatever tone capacitor you have in your guitar with one of the vintage style paper-in-oil tone caps. 1950's technology will never be beat for SOUND. All the modern materials in the world will never sound like these, trust me! The other thing is whatever overdrive pedal you are using, see if you can't use an 18 volt adapter on it in lieu of 9 volts. It gives you much more headroom, response and TONE! To me that is how you can tell a great Guitar Player - TONE! There are lots of players who can play lots of notes but some have the most obnoxious tone. TONE is everything. You can play one note with TONE and shatter a thousand bad sounding notes! There I have given away my secret : )
