The SV20C combines the raw power of the 1959SLP and authentic voice of classic rock in a new portable style. The amp that first defined rock 'n' roll in the 60s has been revised for the present day, while remaining faithful to the original with its Plexi design and all-valve tone. Still considered a classic by scores of legendary guitarists, the SV20C lets you play like your heroes on stage, in the studio and at home.

A bit of a costly amp for a 10’ speaker combo. But it has that amazing plexi sound that is worth every penny. A great investment in your sound.

I will say these are amazing sounding amps. I had issues with the combo version, more specifically using as a cabinet. Brand new it's exactly what I wanted. As time went on I believe a design flawed showed through. The tubes are mounted horizontally directly above the speaker, and when the amp gets hot and rolling I believe the speaker rattles the tubes. It started as a slight hiss overtone when sustaining notes or chords that would resolve before the note decayed, almost a nasty fake overdrive sound layered over, especially on either "2" channel as they are the more bassy channels. Very, very subtle at first and I only noticed it when I mic'd the cab, and thought it was a recording flaw as I could only really tell on playback through headphones, and really only when holding a heavy note/chord for a couple beats or more. As time went on it started to come through the speaker noticeably at living room levels but not at jam levels as it was too subtle to notice over the mix. Took it in for service and one of the tubes was going, not out of the ordinary as tubes can go after 10 days or 10 years there's no way of knowing for sure and that's an accepted part of owning a tube amp. L&M replaced the tube no questions asked as it was only 2 months old, it resolved for a couple weeks then the issue came back even worse. Took it in again and we switched all the tubes with new matched sets, again amazing service from L&M no questions asked, all new amp warranty work (tubes and speakers are covered for 90 days I believe it is) and within an hour of playing it was so bad it was basically unplayable. Please note that when put through an extension cabinet, I tried mine and a friend's 1960, absolutely no problems whatsoever. After the full tube replacement I didn't try the 1960 again due to frustration as I bought the amp specifically for the combo convenience for (home) studio or small venues. Don't let this dissuade you from trying or buying this amp, it could be I got a lemon, it just seems to me to be an unstable design that may be an issue long term. I have been playing for about 10 years through types of every amp brand on the market including Marshall, this is the first time I've seen tubes mounted that way and also the first time I've ever heard that sound issue, my Fender combo amp is 10 yrs old and my H&K head is about 1 1/2 and have played through many other tube amps, you don't know amp love until you've played tube amps. Can't stress enough that I love the amp they absolutely nailed the circuit but the combo left me very upset, please make sure you have a good ear for tube amps and get the extra extended warranty just in case, but it may be worth the extra investment to go the head and extension cab route as I have now done. 1000 thank you messages to L&M for everything done to make this right, truly amazing feeling to know your staff cares so much and took the time to hear me out as first time in with the amp it was hard to reproduce the issue until the amp really warmed up and I kinda felt like a crazy person until that a-ha, there it is moment was confirmed.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
  • USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
