Wizgah's review (This content has been automatically translated from French)" Mythical character of an amp"

Marshall 1959 JMP Super Bass
My head is one of the first JMP, end 69, according to early 70's serial number.

Regarding the characteristics, everything has been said before. Here we have a living wage, plug and play.

But I would add that this head has two inputs on the front and also the two outputs (hence the 4 jacks). In the absence of DI, and you have a preamp out for each channel. One can also have fun at all for bridger mix the sound from both channels, which for my part, I find very distinct.

My head is mounted lamps EH 12AX7 in preamp and JJ EL34 power. Channel 1 sounds very "bright" with good treble slap and second channel seems more suited to low frequencies with a good dose of lower midrange.


This is my main amp and probably will remain so for very long. I use it on bass, a Rickenbacker 4004 Cheyenne and a cab home VBC412 Marshall (normally intended to head VBA400).

The output level of my being low level, the preamp saturates quickly. You decide if it suits you or not for the style of music you play is, however, whether you have an active bass (a-15dB pad may be necessary). Also plan to add to it an oversized cab: I used earlier stages a single 15 "that could withstand 250W ... And it was not the weight. Since I invested in a 4x12 400W cashing, I did finally over afraid of my HPs orbit. I agree with the previous opinion: I never exceeds 3 the volume, otherwise completely drown my group under a barrage of grainy bass and treble angry! a treat:-D

With guitar, you enter the area from clean slightly crunchy. If you are deaf or want to become, you can reach the overdrive, but at a volume almost unbearable. An attenuator will probably need to play in the field of saturation.

Note: the amp also quite hot after a few hours. Ideal for your evening barbecue again!


This amp is more "mid-tidy". The character of my Rickenbacker is also something with a Jazz Bass, the sound is much more "wise". You will not sound Ampeg with this type of head, on the contrary!

I like a 12AX7 preamp in, and the gain and the master are not separated, it growls nicely to the style of music I play (Stoner / Hard Rock). If you want a sanitized sound, go your way.

I play with a pick and get a very musical crunch that really gives life to my instrument. In fact, I rediscovered it: crunchy and crystalline highs, deep bass and rumbling (I play in Drop C) and very present mids (this presence can be adjusted by the knob of the same name for a more "boomy" ).

The EQ is extremely basic, do not expect to precisely sculpt your sound with this type of gear: everything from scratch, you plug and play. That, at least I think, the philosophy of this type of material. This will amplify the characteristics of your instrument, its qualities, but also its faults!


I have this head for 2 years, and this is my first all tube head. I had decided to invest in an amp legendary collection, and I have not been disappointed. If you find a completely original at an affordable price, take the opportunity!

Or the price I got it (1100 euros, revised, and lamps changed completely original), this is a bargain. A must for guitar, amp and a character on bass.

Marshall 1959 JMP Super Bass
It's a head amplifier lights, 4 power (EL34) and 3 pre-amp (12AX7). The lamps are the same as the SLP and 1959 MODELS superlead. The MODEL is manufactured from 1966 t in 1980. In 1976, Has reviewed and Aesthetics in 1980, his place in cda JCM 800 Bass Series. The power is 100 Watts, but then a real amp 100W lamps. Connections are between the two spars and channels for each channel, a Hi and Low .... sincrement but there is no real diffrence between a 4 in contrast to superlead possde channel Hi Treble and Normal, the Superbass has two identical channels Normal, Volume 1 and Volume 2. output, 2 speaker outputs jack 1 / 4. There are no effects, no effects loop for non-plus, Presence, Bass, Middle, Treble, Volume 1 and Volume 2. that's it ... Oh yes, there is a slecteur impdence the rear of which he must be careful not to lose it. It is a prvu amp for bass guitar, but is used by most of the time guitarist. Especially since technology evolves with the latest issue amp transistors.


The configuration is very simple (see Previous). The sound ..... oh yes .... .... Marshall Is that clear enough? For a bass guitar, the amp is plutt''mid-level''but prsence is standard and the awesome power ... with a volume the sound is best dj, Volume 2, all tremble around you, to a large room we think 5 ... cel but takes trs performance loudspeakers. For the guitar is essentially a Superlead or an SLP 1959, but the channel Hi-treble .... Marshall was the sound, but with a little more crunch, but a little less possibility of adjustment ... but a power curve that rises more slowly.
For the manual .... I forget possde A model 1973 bought secondhand in 1986 ... I guess he's getting lost between 1973 and 1986 (smiles).


I play mostly hard rock .. 1970-80-90 it is well suited this style, but for the low, it is all genres.


I have in my possession since 1986, but I have not used the 1998 in 2004. I had some problem during the PERIOD the electronic or not less than five technicians passs above .. To find one that ultimately matter to me ... it went up nine amplifiers that must be handled with care (in fact it is trs heavy with 2 large transformers) do not place it on a case of sound that vibrates a lot (no prob with guitars a.). Submitted little I use, but I have in my possession a pice collection found less and less today (hh spices also!) .. . The things I dplore are important weight, its fragilitainsi that the scarcity of technicians able to do the service .. most are: its presence and power standard, its looks, its rarity (collection). For the guitar ... this amp is Whereas if you like the sound Marshall typical ... for low, it is better today.
