Ashdown ABM EVO III Owners - Anyone else find them noisy?
obbm replied to Linus27's topic in Amps and Cabs
An unterminated instrument lead, i.e. no bass, acts like an aerial and will just pick-up noise and amplify it. That is not a realistic test. Either put a bass on the end or short circuit the connector. -
[quote name='phil_the_bassist' post='535377' date='Jul 8 2009, 08:24 AM']so which bit/where abouts is the op-amp? I've googled it and i was merely informed it was a basic preamp...does this mean its the first stage of the EBMM pre?[/quote] This is the stock SR5 pre-amp. It uses a 4-way op-amp. The first two stages provide a form balanced input for series and single coil modes. This is the way they eliminate any extraneous noise and hum. In parallel mode they just use a single input. If you follow the circuit through then you will see. The two other stages are the eq control. The whole lot, including the pots are mounted on the single PCB with flying leads to the 4-pole switch. If you wanted to use a different pre-amp and retain coil switching then you would need to trace out and build a copy of the input stages of the MM pre-amp. then connect that to your pre-amp of choice. [quote name='phil_the_bassist' post='535377' date='Jul 8 2009, 08:24 AM']Will this only be a concern if I don't change both the pickup and preamp?[/quote] Not really as all the replacement pick-ups for SR5s are wired to allow direct connection into the stock SR5 pre-amp. If you did away with coil switching and hard wired in parallel or serial then you could just drop in any pre-amp. I used an Aguillar OBP3 in mine for a while but it was just wired in parallel mode. I waited 4-years for an MM SR5 pre-amp to come up on Ebay. I strongly recommentd that you send it back to EBMM and get it fixed. Even if you don't use it, it will have a good resale value. Alternatively you could give it to me. If you want to play around then why not buy my Sub 5. It would give you hours of amusement I'm sure.

I've looked into all aspects of SR5 pre-amps including what you are suggesting. Just to repeat what I've said many times before, the coil switching function is an integral part of the EBMM pre-amp and uses the first two stages of the op-amp. Take away the EBMM and install something else and you'll have to decide which of the three selections you want to hard-wire. The alternative is to replicate the EBMM circuitry on a new PCB and interpose it between the pick-up and the new pre-amp. By rewiring and reconfiguring the pick-up from 5 to 6 wires and completely rewiring the selector switch you can do it but then you lose the switched gain adjustment that compensates for different levels when coil switching. I know I've been there and done it. Tread carefully.

[quote name='attackbass' post='529796' date='Jul 1 2009, 05:33 PM']ive seen this but i cant find the caps they have there anywhere? any ideas thanks tho![/quote] Sometimes you might still find those old value ceramic disc capacitors however the closest modern equivalents are 0.047uF and 0.033uF. The difference in values will have a minimal effect. You can get 0.047 and 0.033 Sprague Orange Drop caps from Watford Valves.

[quote name='PapillonIrl' post='529634' date='Jul 1 2009, 02:50 PM']Really like this.... If you are interested in sending it to Ireland, please get me a rough quote on the postage. Very tempted. Cheers, Nathan[/quote] Looks like in the order of £65 insured.

Wednesday bump.

Wednesday bump. This is a great bass. Does no-one have anything interesting to trade? If it doesn't go then I'll have to break it up and sell the parts. -
Truly tragic to lose one so young. Sincere condolences to his family.

You ought to come and try the MM Sub 5 that I have on sale. It's what an SR5 should have been. -

[quote name='steve-king' post='526557' date='Jun 28 2009, 10:36 AM']Hi, please excuse the ignorance from a novice, but when you say a SR5 profile neck, do you mean as you would find on an Ibanez? Thanks, Steve[/quote] SR5 is a common abbreviation for the "Musicman Stingray 5" or more correctly the "Ernie Ball Musicman Stingray 5", which is a bit of a mouthfull.

I bought this is a fit of madness thinking I needed a spare 5-string but in reality I don't and as my gigging is going to be curtailed shortly it's up for sale again. More picture [url="http://basschat.co.uk/index.php?showtopic=51796&hl="]at the original thread.[/url] Its history is well known to the Forum. It's a Musicman Sub 5 stripped of its tasteless black paint and electrically upgraded with a custom John East MM style 3-band pre-amp which has bass, treble and Swept Mid. With the latter in its centre detent position you get pretty much a 5-string with a classic 2-band MM sound. I'm pretty sure the neck is exactly the same dimensions and profile as a stock SR5. It comes complete with soft case, original pre-amp, clear scratch-plate. Last time it was up for sale silverfoxnik posted: [quote]This very nice vintage 'Ray look was created by the Beedster and the John East pre was built to his spec too, so it's quite a unique bass. My memory of it is that it had a lot of tonal variety thanks to the sweepable mid e.q. and it was light and comfortable to play.. One other good thing was that for a 34" scale bass, the B string is really excellent on this, as it is on a lot of Stingrays.. Oh, and I sold it on because I wanted a passive 5 string, otherwise I would have kept it. Gave me a bit of nostalgia seeing it just now I must admit and it has had a few BC owners who may well feel the same; Beedster, me, WalMan, JoJo Bass (I think) etc, etc.. So it's done the rounds, but don't let that put you off..It's a good bass!

Good luck with the sale; certainly a lot of bass for the money![/quote] I agree it is an excellent bass. £400 plus postage if required or could be interested in trades, etc. Try me. PS. I hope nick80 won't mind me using his pictures. It's such a nice garden.

Funnily enough I have an almost identical pair like that. Well done. Good choice.

I went through something similar last year Al. Don't give up, just take a break, give it some time and it'll all work out OK. I must admit that Crete sounds and looks very attractive.

Basschatters playing with 4 of the 5 bands at Broadbridge Heath Beer Festival yesterday, near Horsham, Sussex. [i]Flying Visit[/i] with Craigonbass / Fender Jazz [i]Whatever[/i] with Sixshooter / recently rebuilt blue '55-alike Fender Precision [i]Six Miles Away[/i] with Maxcat / Bongo 4 / Stagg EUB [i]Amity[/i] with obbm / MM StRay 5 everybody played though sixshooters' vintage Trace rig. Fortunately the weather was kind and a good crowd turned up to help raise money for Shelley Primary School. There's a similar event next Saturday at the famous Loxwood Beer Festival with sixshooter and myself playing with our respective bands. We'll be joined by Stingrayfan and his band Wag The Dog. Starts around lunch time and goes on until 11.00pm. Please all pray for fine weather again.

[quote name='Happy Jack' post='512641' date='Jun 13 2009, 10:07 AM']Are you sure about that Dave? Mine weighs less than 4Kg - I usually say 8.5lbs - which is a manageable weight for my shoulders.[/quote] It was the bathroom scales with me as well, also the J-Retro and battery weight almost 0.35 Kg. Best measurement is to come and play it.
