GE-Style 6L6GC with a short bottle and black plate.

The Classic Sound of the 1950s and 60s - Excellent Tone, Maximum Lifetime!

The perfect choice for vintage tweed and blackface amps such as the 1960 Bassman, Twin, Showman or Super Reverb. The complex midrange and sweet heights are a class of its own. The TAD 6L6WGC-STR is our recommendation for classic tone with warm cleans and rich, sweet mids when pushed. Great for fat jazz or blues tones.

The TAD 6L6WGC-STR is a remake of the small bottle GE6L6GC and has the same warm lower midrange and silky top end as the classic GE versions of the 1950s and 60s. Like the historic RCA 5881, this tube features exclusive blackplate anodes and a side getter. The TAD 6L6GC-STR and the TAD 6L6WGC-STR have our exclusive black-plate desings, gold grid wire, double getter construction, no-noise filaments and 1.2mm thick heavy duty glass. This tube is only 80mm high (without pins) and can replace 5881 or 6L6WGB tubes.

This has been my preferred 6L6 tube for a few years now. A bit stronger mids and softer overall tone than a large bottle 6L6. This isn't a huge factor with my setup, but the short bottle type also distorts more readily. Great sounding and well made tube.

I have been using this power tube exclusively for several years now. It is a short bottle 6L6, and to my ears it is a little more controlled in the lows, a bit stronger in the mids, and overdrives sooner than a typical length 6L6. Very well made and reliable in my experience. I use 4 of these in a Peavey power amp along with my Mesa Boogie Studio Preamp. I really hope TAD can find a new manufacturing plant for these after the pandemic (the main reason I recently bought 2 spares).

These are great tubes in a Fender style amp. I'm also using the TAD 7025 in position one and this combination has tight low end with silky highs. Probably the most positive, pronounced change this amp has experienced to date! Service was typically the best!!

I bought these tubes to replace the power tubes in a Fender concert pro tube series guitar amp. I really like the way they sound! They break up nicely when pushed a little, but sound great clean at lower volumes! Makes my amp sounds better all around! Very satisfied!

Great sounding tubes! These really pop in everything I've tried them in. They sound like a mix between an EL34 and the traditional 6L6GC, with the latter's power output.

Over the years, my main choice of power tubes has always been the TAD 6L6WGC. I think the reason is that TAD 6L6WGCs are long-lasting, rich in 2nd order harmonics, exceptionally quiet, possessing an abundance of clean headroom, and comparatively low cost compared to other NOS tubes. My current amp is a Brunetti 35W Singleman 1x12 combo, and although the stock tubes were Tung-Sol power tubes, the Tung-Sol tubes wore out sooner than my experience with TAD tubes, and for that reason, among others, my choice has been TAD 6L6WGC power tubes for all my amps that are 6L6-based.

Over the years, I've grown accustomed to the superior quality that TAD 6L6WGC power tubes offer...high headroom, extended lifetime, smooth overdrive response when pushed towards breakup...I've heard other power tubes, but none can compare to the quality and value of TAD 6L6WGC tubes...

These TADs were great. Got rid of the treble spikes, nice and smooth.
