No Sales Tax For Customers Outside Of California.

Guild amps have long been stealthy, sneaky value prospects for those who knew about them.  These days, they're moving out of obscurity as more go down the tone rabbit hole.  Regular mentions in the Truth About Vintage Amps Podcast have contributed to the upsurge when they're discussed as a way to get great tone for around $1000.

When this one came in I figured I would have to do the standard service - filter caps, a new power cable, etc.  The work had already been done, recently and professionally.

The original Jensen speaker was toasty however. so I replaced it with a Jensen C12PS that was recently reconed by Speaker Repair Pros.  It is a great match for the amp.  The speaker is dated to 1966.

The basic fact that the amp is built for tone coupled with the beneficial service means that you get a little beast that sounds killer and runs solidly, ready to go for the next 20 years.  It is also a small, light package to tote around.

Some info on the amp from the interwebs:

The Guild 66-J Amplifier is a classic piece of gear from the late 1950s to early 1960s, renowned for its warm, dynamic tube tone and vintage character. This amp features a 1x12 Jensen speaker and utilizes dual 6V6 power tubes, delivering around 20 watts of power. Its design takes inspiration from Fender and Ampeg circuits of the era, offering a tonal palette that combines rich, warm cleans and smooth overdrive when pushed.

The 66-J includes a bias-vary tremolo effect, controllable through dedicated strength and speed knobs, making it a versatile choice for various styles, from rock to jazz. With separate bass and treble controls, along with dual channels, it provides a range of tone-shaping options. This amp is also highly regarded for its ability to pair beautifully with pedals.

Visually, the 66-J features the classic tweed or leatherette covering and oxblood grille cloth, adding to its vintage appeal. The compact size and solid build quality make it a practical choice for both gigging and studio use. These amps are relatively rare, adding a layer of exclusivity to their appeal. Overall, the Guild 66-J offers an iconic vintage sound and aesthetic at a more accessible price point compared to its contemporaries
