any experience with Ibanez Promethean heads?

Recommended Posts

Hi, guys!
I'm just trying to figure out if a Promethean head might be the right amp for me.
I currently own a GK MB200 head, playing to a GK MBE 210 cab (1. gen. with neo elements). This amp sound a little harsh and boomy to me playing my JV Jazz Bass. (Have to cut back the bass and treble a lot)
An Ibanez Promethean head (P500H) has surfaced on a sales-page here in Norway for about the equivalent of £130. I have read many good things about this amp, but nearly nothing newer than 2015 or something. ( I know it's discontinued). I also read about the slow start issues, and will ask about that if I contact the seller.
So. Is it fair to believe that the Promethean might give me a different sound going through the same GK cab?
Can the eq and "vibe"(?) knob make it a little "warmer" sounding, with less of a mid scoop?
Does anyone have these anymore? experience With both would be awesome.

PS. Other amps i have been looking at in the 500-800w range, cost from £300 up used...

Thanks in advance.

Not sure about the Promethean head, but I recently bought the little P20 practice amp & it's brilliant. Very well-but with a good range of sounds from such a little monster.

If the head is anything like, I imagine it's very good.

I used to have a GK MB210 (the 500W combo version with the 2x10).  I also still have a Harley Benton BA500H which is pretty much the same thing as the Promethean.  It is my back-up amp and it sounds really nice with a P bass with flats through an old 1x15 cab and my particular playing style.  I would say yes, it's easier to dial in a warmer tone compared to the GK.  But there are so many variables involved.  To take a different approach - how about a Zoom MS-60B, B3, or B1 pedal?  You can plug this into your GK.  It has many amp emulations built in, and flicking through them and tweaking is a lot quicker and cheaper than buying & selling heads when you are searching for your best sound or experimenting with all the options.

Thank you for your replies.

I am looking for a second amp head anyway, so I thought I might try the Promethean. Get a little more power as well as have the ability to rehearse together with my 15 year old, who is just starting to learn. I play only as a hobby, so budget is tight. No paying gigs at the moment...

I used to have the original Promethean combo, which featured the head you're talking about.

It's an awesome piece, very loud with a nice warm tone. The graphic EQ is very useful and all in, if I'm honest, I wish I'd never sold mine.

I have no idea why on earth they stopped making them, but it was a bad move. The newer ones are a bit pants...

If I was you I'd go for it 😎

I remember the warm and round tones and power coming from a 15" combo I used on a gig once. I was impressed by the sound of this little Ibanez. I think it's a good amp for the price. Good luck.

      Another one on the chopping block that I'd like to keep but can't/shouldn't 😛
      Japanese Ibanez Roadstar ii RB750 BK with custom made pickguard and backplate.
      Its in great condition for a 35 year old. Bit of minor buckle rush and dings in the usual spots (top of headstock etc) but very minimal fretwear, truss rod works well and pups and bridge adjustment screws all work well with no rust. Neck front and back is in great shape too.
      The pickups on this are really decent, separate adjustable pole pieces and have nice slightly aggressive growl and med to high passive output (very slightly less output than my Yammy BB424x but more than a Geddy CIJ Jazz I tried it against if anyones interested)
      I've given it a decent setup for low/med action and decent intonation and its wearing a newish D'addario med nickel rounds with loads of life in em still.
      From Guitar Data Project:
      Your guitar was made at the 
      on July, 1984
      Production Number: 5038 
      Did a bit of research on this when I got it an its a bit of an oddity it would seem. So its a 21 fret neck and all the other images and old catalogue pages I can find are 24 fret, including this one thats selling at the Bass Gallery at the moment:
      Know there got to be some awesome 80s Ibby aficionado on here that can shed some light on things. The one 21 neck I could find on the net was this guys review of this model:
      Was a difficult one to  price up with the mods and little other info so feel free to give me thoughts on value as well, especially if you think I can get more for it 😂
      Collection, Coffee and Try outs in Forest Hill. S.E. London or I'm gigging regularly around the UK a fair bit so a meet up is possible.

      Up for sale is my Ibanez SR3006e 6-string bass
      This was handmade in the Fujigen factory in Japan in 2005, and consists of a 2-piece mahogany body, 5-piece wenge and bubinga neck and wenge fingerboard, Bartolini humbuckers, Ibanez Vari-Mid circuit with vol, pan and 3-band Ed with sweepable mid range that does a passable impression of a Wal, lightweight     Gotoh tuners and Monorail bridge. It has some signs of wear considering its 14 years old but is in excellent condition. The wood work is superb and the wenge grain on the neck is fabulous (as is the mahogany on the body). I believe this was Ibanez’s attempt to compete with Warwick as the woods are similar, and the tone is excellent as a result - a bit darker than a Warwick but the bottom B in particular is epic - very tight sounding even far up the neck and the whole bass is even sounding bottom to top. Electronics are noise free and powerful (and the vari mid circuit is actually better imho than the current circuit in the 5000 series - more flexible). 
      The bass comes with the original hard case which is also in excellent condition
      I’ve had many high-end 6-strings and this is easily as good as anything I’ve played in terms of spec, fit and finish and tone, and being rather rare it’s quite a bargain I think!
      Price is £650 ovno - I can post but it will be UPS with full insurance so will be at cost and extra. I’m not desperate to sell so happy to hang onto it if there is no interest.
      Any questions, just ask!

      Ibanez Talman shortscale. Selling as iylt just not being played around here and with a little 'un on the way I need the cash more than I need the bass!

      Up on the block is this lovely Ibanez Blazer. Has some wear but this is a real workhorse of a bass and it definitely looks the part. Frets are in good condition and have plenty of life left in them, truss rod works and everything bar the knobs are original.
      Collection in Jersey is an option if you fancy catching the ferry and enjoying our beaches at the same time or I can post in a gig bag with tons of packaging, just let me know where you are and I can get a quote.
