Marshall's Legendary DSL Is Back in Action

The Marshall DSL40C 40-watt guitar combo amp gives you the definitive essence of British tubularity. Reigning supreme for a decade, the DSL series enjoyed worldwide acclaim. So, with a nod to pent-up player demand, Marshall presents their new, all-tube DSL series. Amazingly affordable, the DSL40C combo fortifies your tone arsenal with impressive power and the tastiest tonal qualities and features of both modern and vintage Marshalls - in one highly tweakable and portable package. From glassy cleans to bone-rattling crunch to blistering high gain, your wish is the Marshall DSL40C's command.

Marshall DSL40C 40-watt All-tube Guitar Combo Amp at a Glance:
  • The DSL series - a revered tonal heritage
  • A 40-watt tone beast
  • Two channels and all the trimmings
The DSL series - a revered tonal heritage

The Marshall DSL40C hails from a revered lineage. Marshall introduced the JCM2000 Dual Super Lead (DSL) series amps in 1997. Right from the beginning, these all-tube monsters enjoyed enthusiastic approval by guitarists and the press alike, forming the backlines of top acts in all musical genres and bludgeoning audiences worldwide for a decade before being replaced by Marshall's JVM series (a musical powerhouse in its own right). Considered the go-to rock amp by many tone-savvy guitarists, there is considerable pent-up demand for Dual Super Leads. Marshall hears you and is proud to introduce the new-and-improved DSL series.

A 40-watt tone beast

Marshall's DSL40C is an all-tube, twin-channel workhorse capable of conjuring any classic Marshall sound - past or present. Four ECC83s in the preamp section (in concert with the amp's gain/master volume arrangement) give you stunning tone-shaping mojo, and with two EL34s in the engine room, you have the volume to rule any club in the world. Sporting the same tubes (minus two EL34s) and feature set as the original DSL100, Marshall has gone on to fit this little beast with critical upgrades that give you even more control over your sound. A Resonance control (as opposed to the original's fixed deep switch) lets you dial in your preferred amount of low-end girth. You also get studio-grade digital reverb (instead of spring), a rear-panel Pentode/Triode switch that drops the amp's power to a studio-friendly 20 watts, and a bypassable rear-panel series effects loop. Marshall has even included a 2-way footswitch for channel switching and reverb on/off.

Two channels and all the trimmings

The Marshall DSL40C sports two footswitchable channels: Classic Gain and Ultra Gain. Each channel boasts two modes: Clean/Crunch and Lead 1/Lead 2, respectively. With the DSL40C, you can go from glassy Plexi-esque cleans to JCM800-style snarl, hot-mod 2203, face-melting high gain - and everything in between. To shape all this delectable Marshall tone, you get flexible, shared 5-way EQ (treble, middle, bass, resonance, and presence) juiced with the thoughtful inclusion of a Tone Shift button - ideal for scooped modern metal mojo. The DSL40C is ready to rock. Are you?

Great amp & tone

Simply said, best of both worlds. You get the great Marshall sound from the DSL40CST, and a great speaker, too. I have heard these combos with the regular Celestion and the Celestion Creamback 65. Night and day, Creamback wins! Plenty of headroom for most outings. Does the bedroom levels really well, thanks to the 1/2 power switch. Built like a tank, and I feel comfortable knowing I will not need a backup at the show. I believe the tubes are Marshall branded "JJ's", which are fantastic for this amp. Give this combo sometime to break in well, and the Creamback 65, too. The character of this amp gets better and better with time after the break in period. I have read reviews of people saying this amp has too much treble, but I am sure they did not give it time to breakin, and they don't have the Creamback. I have not experienced this, and I play a single coiled Stratocaster and a Les Paul. No issues! I would like to mention the Sweetwater team, and my sales engineer, Patrick Weaver. In my humble opinion, Patrick has been there for me with all my purchases, from point A to point B, and I would strongly urge anyone reading this, and considering this pedal to deal with Patrick. Very professional minded and is product smart to answer any questions. I am very pleased with making my purchase of this product through Sweetwater, and will continue to make more purchases in the not so distant future. Thank you Sweetwater!

Less is More

I'm impressed in the variety of tones you can get out of this amp without having to force it. Marshall has done a great job creating a complete package at this price. I'm even more impressed with the service I received from Phil Schwan and Sweetwater. Thanks guys!

Marshall ROCKS!!

Came in one day late due to snow in Memphis, but got here the next day. Came in with new Les Paul Traditional, at the lowest price on the 'net, and when I hooked it up, watch out! This is what a Marshall amp is supposed to sound like. Simply amazing. Thanks to Aric and the staff at Sweetwater.
