The DSL-1C and DSL-1H are all-valve, 1 Watt 

amplifi ers voiced to reproduce the sounds of 

the Marshalls of the ’90s but at what Jim liked 

to call a ‘home friendly’ volume.

As already mentioned, there were a number of 

very successful Marshall amps in the ’90s, all 

worthy of representing the decade. The DSL100 

however was a true revelation that leading 

critics dubbed ‘the ultimate Marshall’ as it 

represented the perfect marriage of modern 

fl exibility, high gain capability and features 

with the signature ‘roar’ of the 2203s and 

Superleads. The DSL-1s have been designed to 

provide these distinctive tonal characteristics 

at the surprisingly loud level of one Watt.

To add further to the ‘home/studio friendly’ 

nature of this amp, whenever the full 1 Watt 

output proves too loud you can hit the Low 

Power button on the rear panel to further drop 

the volume - enabling you to crank the volume 

to get the tone you desire.

Overview

ENGLISH

Follow all instructions and heed all warnings.

KEEP THESE INSTRUCTIONS.

Warning:

Before going any further, make sure that your amplifi er is compatible with your electrical supply. If you have any doubt, please seek help 

from a qualifi ed technician – your Marshall dealer can help you in this respect.

Mains Input & Fuse:

Your amplifi er is provided with either a detachable mains (power) lead which should be connected to the mains input socket on the rear 

panel of the amplifi er or a fi xed mains (power) lead attached to the rear of the amplifi er. 

The specifi c mains input voltage rating that your amplifi er has been manufactured for is indicated on the rear panel of the amplifi er.

The correct value and type of mains fuse for valve amplifi ers is specifi ed on the rear panel of the amplifi er. 

NEVER attempt to bypass the fuse or fi t one of the incorrect value or type.

Transporting your equipment:

Please ensure that your amplifi er is switched off and unplugged from the mains electricity supply and that all removable cables have 

been disconnected from your equipment before attempting to move it.

Important set up information:

1.  Make sure that the cabinet(s)/speakers, where appropriate, are connected to the correct impedance LOUDSPEAKER jack(s) on 

the rear panel of the amplifi er. See the Speaker Output guides in this handbook, if applicable, for specifi c information regarding 

impedance matching. When using an extension cabinet make sure that you are using a proper speaker cable. Never use a screened 

(shielded) guitar cable for this purpose.

WARNING!

 Failure to do any of the above may damage your amplifi er.

2.

 Ensure that the VOLUME controls on the front panel are set to zero.

3.

  For amplifi ers provided with a detachable mains (power) lead, connect the supplied mains (power) lead into the MAINS INPUT on the 

rear panel fi rst and then into an electrical outlet

4.

 Plug your guitar into the INPUT jack socket on the front panel.

5.

 Turn the front panel POWER switch on and, if a valve amplifi er, wait a couple of minutes before going to point 6.

6.

 Turn the volumes up to your preferred level and your amp is ready to play.

This is the fi rst Marshall product manual in living memory not to include an introduction from our 
Guv’nor, the late, great Jim Marshall. Although the DSL-1H & DSL-1C had been blessed by Jim both 
sonically and visually, he left us to go to a far better place before we started work on the manual. 
That said, a couple of choice quotes from our much missed leader are included.

Thank you for purchasing this DSL1 - one of a Limited Edition Series of British made, all-valve, 1 
Watt amps celebrating Marshall’s 50th Anniversary. All told this series will comprise of fi ve different 
pairs of heads and combos - each pairing paying tribute to the sound and aesthetic to one of the 
fi ve decades that make up our fi rst 50 Years of Loud. The DSL-1 you are the proud owner of is our 
homage to the glorious ’90s. This particular decade was a diffi cult one to tie down to one amp as 
we had several very successful valve products during that time - the JMP1, the 30th Anniversary, 
the JCM900s and the JCM2000 Series which comprised of the DSL and TSL ranges. 

“They were 

all wonderful amplifi ers and that makes the ’90s a particularly tricky choice,”

 Jim stated when 

the series was being tied down. 

“As we have to pick one amp to represent Marshall’s best in that 

decade though, my choice is the DSL as that series really did get everyone excited. From the artists 
and the press to our many loyal customers, the DSL really seemed to touch a positive nerve.”

 Let it 

be written, let it be said. DSL it is.

As Jim always closed his introductions with: we sincerely hope you enjoy your new amp. We know 
it will bring you countless hours of playing pleasure.

Welcome to the Marshall family!

Sincerely,

The Marshall Team

As on the acclaimed DSL100, 

the Classic Gain and Ultra 

Gain channels, share the same 

tone controls. The Classic Gain (Channel A) of 

your DSL-1 gives you that harmonically rich 

clean and edgy crunch reminiscent of a Plexi, 

while the Ultra Gain channel takes you into the 

open, high gain territory of a hot-rodded 2203. 

These two channels are footswitchable via the 

supplied footswitch.

In addition to the standard Treble, Middle 

and Bass controls, the Tone Shift and Deep 

switches add further to the tonal fl exibility of 

your amp. As do the FX Loop and Speaker 

Emulated Output found on the rear panel.

The combo is fi tted with an 8" Celestion 

speaker specially voiced to provide the best 

balance between a compact size and a full 

sound. Both amplifi ers are also very happy 

driving a full 4x12" cabinet for the ultimate in 

mini Marshall ’90s tone.
