For life

By psYchoActiF, 25/04/2014
All lamps, although 90's. Sharper than the JCM800 series. 100W, impossible to fully, but can adjust to 50W.


Equalization is very limited, but the sound is there.


I have the combo version with 1 HP, combined with LAG The Beast Supreme Custom Shop 97 too, ba it smashes.


Bought in late 1997 after a summer in the fields of cocos in Brittany, this amp is always with me, and I do not divide them. A small problem during the warranty after service return that say ... Almost 20 years ago, and just a change of lamps. Indestructible.

Very good versatile amp

Amp originally fitted with 4 x 5881, I did change to support 4 x EL34 "Mulard".
Amp 100W, 50W in swtichable (triode: loses power but also the characteristic)
2 foot switchable channels.
Channel A: clean -> crunch
Channel B: crunch -> overdrive
Loop insertion effect balance with -10 / +4 dB


2 amps easy to use switchable channels


Suitable for Blues, Rock and even Metal.


Used since 1998
What I like: Channel A cranked overdrive with a good front.
I also like: changes made to the channel B (diode bridge split) which gives a closer rendering JCM 800 punch.

guizmo238's review

100 watt head lamps .... The settings on this head are not at the forefront .... not much opportunity since SETTINGS pots do not respond on a large beach .... but we can solve this small lacunne by purchasing a pedal of equalization (boss ge-7 for me) and you realize that some things holds big!!


For my part, the configuration is quite complicated .... I have two speakers who will lead in 1960 with A + B. ... connectivity is quite complicated, I had to look on this site for the information necessary .... but with good advice I got I am absolutely very happy!! I did not get a manual with but at the price I paid I even had the 1960 A cabinet with!! sound of the amp is very good if you look for rock sounds .... but we must add effects to get the big sound ... its very hot and the distortion is effective wish a very good clean and also easy to find!


I like metalheads and rockeux .... this is the amp of choice for my type of player .... I use a digital delay, a chorus and a set of preamp eq ... j ' addition follows a ibanez tube screamer overdrive for Narrow my sound and have the teeth to the metal ... the sound is really good ... in 25 years it is my hobby and best sound is the sound I was looking for! !


it's been 5 months that I use and I'm very satisfied ... nothing to do with the small combo amp and other fine good cheap!! that I like the most is that it is big, yes, but the sound is diffuse Surprisingly ... with 8x12 inches behind the ca pouuse and spreads halucinante way!!, as I bought it used, I can not I really pronounced on the value for money but in my opinion worth it ca pay dearly for this type of amp .... moin has to have a changing temperament, he will follow me all my life I think so! !

Almost 20 years of loyal service

Lamps (Power & eq) 100w 2 channel
I'll spare you a description ... eq for each channel it could be fun! but are not!


There is no simpler, no need to adjust the hours it sounds!


I played noisy, punk, rock, indus, with a rise of 70 SG DiMarzio, a Mustang Us, a Heritage ... and never disappointed! In Briefly, crystalline or clean sounds I do not know, although with the Mustang and the channel A of the amp the sound is more than respectable wholesale with single coils it goes well, we can play funk fusion Red Hot ... but we chose not to its characteristic crystalline Marshall ...


I use that since there is, I'm also JCM800 master volume and a few others but this one I do not loose! The scratch who tested it all appreciated . But then I tested the version with the 5881 and there I found no sound, nothing to see, I also tried the 2000 I can not find it better with buffs that are useless if not have a sound yucky!
This is an amp that is not expensive OCCAZ and with a good selection of lamps it does! Otherwise the little negative point is that the knobs spit, as usual! After years of bomb I'll have to contact me decide to change them!
