Rickytwo Posted July 18, 2020 Share Posted July 18, 2020 (edited) Price Dropped to £200 24-9-24 Part of my Retirement Sale - Please see other items If you are looking at this then you probably know exactly what it is and what it is capable of. If you have any questions re power, dimensions, weight etc then please give me a call. SWR SM900 Amp see details below Here's more details from SWR; The SM-900 is truly the “State of SWR’s Art” in bass amplification electronics. The SM-900 is only slightly deeper and heavier than the SM-500, yet delivers twice the power and includes new fea- tures such as our very flexible tone section. Along with shelving-type Bass and Treble controls, the equalization section consists of two independent 3-band semi-parametric EQs. This provides the user with two analog presets via a silent footswitch, or three presets (EQ 1, EQ 2, or EQ 1+2) using the manual slide switch located on the front panel. You can now go from a solid groove sound to soloing with just the tap of your foot. Several suggested EQ settings are included in the tone section of this manual. The SM-900 also boasts a studio-oriented “side chain” effects loop allowing the user the diversity of an effects unit while maintaining the constant clarity and natural tone of the instrument. SWR’s exclusive “To Tuner” jack is also on a side chain. Remember when you had to unplug your bass from your amp and hook into your tuner and frantically tune up between songs? Or patch the tuner between your instrument and amp, thus degrading sound quality? Those times are history. Add to the above both stereo and mono effects loops, stereo/mono operation of the power amps, biamp capabilities, up to 900 watts RMS of power, an extremely quiet preamp, a “non-pumping” limiter, complete recording ability, and SWR’s proven reliability and sound quality, and you have what we feel is the best bass amplifier made anywhere in the world. Every Professional Series product from SWR Sound Corporation is manufactured and hand-built in Sun Valley, California, USA.

HazBeen Posted July 20, 2020 Share Posted July 20, 2020 This is an amazing deal, I still resent the fact that Fender bought one of the best amp builders SWR and killed them off. Someone should buy this, as it will deliver great tone in spades. 1 1 Quote Link to comment Share on other sites More sharing options...
Rich Posted July 20, 2020 Share Posted July 20, 2020 An absolute classic, one of the finest bass amps in the history of, errm, bass amps. Certainly one of the best I ever had. And this is a proper bargain. 1 Quote Link to comment Share on other sites More sharing options...
bassmayhem Posted August 4, 2020 Share Posted August 4, 2020 These amps are classic! I believe it has the weight of a Morris Minor, eh...? Is the effects chain fully stereo? Quote Link to comment Share on other sites More sharing options...
deepbass5 Posted January 12, 2021 Share Posted January 12, 2021 Great Gear - I've been advertising my SM500 for more than this. A bargain. No one is making gear this good anymore. 1 Quote Link to comment Share on other sites More sharing options...

Paneum Posted February 4, 2021 Share Posted February 4, 2021 Hello, still available? And would you consider selling it to someone outside of UK? Quote Link to comment Share on other sites More sharing options...
Rickytwo Posted February 4, 2021 Author Share Posted February 4, 2021 Hi, Yes it is. I've had some interest but nothing firm yet. I've no problem selling it outside of the UK providing I've received cleared funds and that you've arranged the courier. Please note that the amp is heavy as is the yellow box type mains electric converter. It could therefore prove quite costly to get it to you.

Owen Posted April 1, 2021 Share Posted April 1, 2021 A very long time ago I had Boogie D-180 head which needed a stepdown transformer. I asked the guitar shop if there was any way of doing away with it. They said no. So I carried it around. Then I asked my brother who is a qualified Electrical Engineer and he opened it, took a different tap off the mains transformer (apparently!) and I could plug it into the wall quite happily. I am NOT saying you can definitely do that with this, but it would certainly be an option to look at. A proper tech (likely to NOT be your local guitar shop) could change the internal transformer in the amp and it would be all good. At this price you would be a fool not to snap it up if it even remotely matches your amp needs. 1 Quote Link to comment Share on other sites More sharing options...

Rickytwo Posted June 24, 2022 Author Share Posted June 24, 2022 Hi, your post has prompted somebody else to PM me about the SWR amp. Just a quick and honest heads up, you asked about it first.... Am gigging tonight and leaving at 4.30pm so will pick up any responses tomorrow Quote Link to comment Share on other sites More sharing options...
dmccombe7 Posted July 16, 2022 Share Posted July 16, 2022 Had an Ampeg SVT4 Pro US built and external transformer. Local tech changed out the transformer completely with part supplied from Ampeg. Was back in 2012 and cant remember what cost was for the Ampeg transformer. Looks like a fantastic amp too. Dave Quote Link to comment Share on other sites More sharing options...
Owen Posted July 16, 2022 Share Posted July 16, 2022 I had a US spec Boogie D180. Local amp tech said it was unconvertable. My brother who is an electrical engineer and more motivated took a different tap off the transformer and it worked like we would all hoped it would. 1 Quote Link to comment Share on other sites More sharing options...

dmccombe7 Posted July 16, 2022 Share Posted July 16, 2022 Might be worth showing a pic of the inside and the transformer as it could help someone decide. The external transformer you are using looks a bit on the hefty side. I had a smaller one for the Ampeg SVT i eventually got converted.

BassBod Posted October 19, 2022 Share Posted October 19, 2022 SWR's were fitted with transformers that had taps for various international voltages, so they could be safely wired for UK voltage. However they stopped doing it around the late 90's as I recall, possibly a bit earlier. The stuff with "SWR Engineering" written on the back was multi-tap, but later amps with "SWR Sound Corporation" probably aren't. This is from memory, so dates are approx. The company got sold to its accountant...say no more... Quote Link to comment Share on other sites More sharing options...
G-Lo Posted March 7, 2023 Share Posted March 7, 2023 (edited) There's one near me for sale for 300 euro... seems a bit of overkill seeing as I just bought my first bass after 20 years and wnt something for occasional home practice.... or is it 🤔 Edited March 20, 2023 by G-Lo Deambiguising Quote Link to comment Share on other sites More sharing options...
