Amp sounds great and is loud. It does not perform like the 100 watt version in a band situation, so don't expect that. Due to less wattage I'm guessing, it pushes much less air. I bought thinking I could replace my 2203 and save my back etc. It didn't cut it live. Not due to sheer volume, because it has plenty of that, but lack of...? Something like that... However, it does sound great and is a good re-creation of the original, in a smaller sound space, if that makes sense. I would never part with it as its a great substitution to have at home. My 2 cents.

Comparing this amp to my original JCM 800 (2204), I can say that this one is a faithful reproduction. Tone is bang on. The only difference is that this amp has less bass, which you have to expect from the lower wattage. Also note that you need to run it on 'high' (20W) to get the best tones. (5W mode is a bit spongy)

I got the Marshall SC20H head and the matching 2x12 cab. This combination nails the JCM 800 rock sounds I remember from the 80's but in a smaller package...very nice! This is my first real Marshall (tube amp) so coming over from Mesa amps it took me a little while to get it dialed in just right but once I figured it out it was amazing. I can get some really nice tones in the 5W mode (using a loop pot to keep volume manageable) but the 20W mode is killer. These amps are Loud, even the 5W mode is very loud if you turn it up. The 20W mode is definitely not for home use unless you live in a mansion or have access to a barn or attenuator. The SC20H sounds best when the master volume is 5+ and this is where the Magic really happens! If you have access to a good quality attenuator then you're all set. I would highly recommend putting an SD-1 pedal in front as a boost (level at max, drive at zero), especially if you have to play at lower volumes. For home use a reverb/delay in the loop at a moderate setting adds some sparkle. The stock tubes are good. The controls on the amp are very responsive. It takes pedals well. The V-type speakers in the cab complement the amp well. I play mostly classic punk and hardcore (Sex Pistols, Dead Kennedys, Circle Jerks, Black Flag) and I find this amp has more than enough gain for anything I would play. For lower gain it also does classic rock really well. AC/DC tone was easy to dial in. I highly recommend this amp.

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.
