Bassbod, Thanks for the tips. Twiddled and plugged/unplugged. I am certain battery is new. And I tried two Modulus basses and get same or similar levels of distortion on both. I did try the Flea through a combo in my local music shop and through a Marshall 10w guitar combo and didn't get the distortion. Tried Flea bass and stingray through fx return, no distortion, actually louder than plugging into front jack but no tonal adjustments etc possible. Plugged into the front input and get the distortion with eqs at 12 o clock, with the contour voicing filter in or out. This at both volumes at 2-3. Any ideas? JJJ

Spot on! I'm spoilt for choice now. Thanks all. Jjj

Ordered and received speaker the other day, it's now fitted and panels and tops put back on. No problem with passive basses and a Stingray so far but my Flea bass causes distortion at low volumes (e.g. At levels permitted in the sitting room). I have got the pre vol lower than the post volume, and I have also rolled all the eq's back. I seemed to get a big jump in distortion when I put the 1kHz up to 12 o clock as well as when the tone knobs on the guitar are turned up. Is it possible that the output of the Modulus bass is just too high for the amp? For the info the pickup is Lane Poor and preamp is a Bartolini. Any suggestions? Feeling quite gutted now. Btw the speaker was definitely knackered so that repair was probably coincidental. JJJ

Evening all, My bridge has a screw missing (see pic) and I need a replacement. Looked at a few websites and emailed a few but have been told they don't stock them. Also tried contacting Fender but no response as yet. I am guessing they are imperial and an American thread but don't know what. So the question is where can I get one or what is the thread/size. Need to get this back on my well worn Precision! Cheers jJj

Here we are, for those of you that may be interested in the internals of a 200MB, here are some pics. First two: side views Pic 3 pre dusting, so much dust and disintegrated surround. Pic 4 dusted and hoovered Pic 5 lots of lovely large components! Plenty of screws to undo (48) but surprisingly easy. The hard bit will be putting it back together without rattles etc. will order speaker tomorrow. Will also report on progress. Cheers JjJ

Thanks everybody. This is the picture that tells the story, I noticed a dark area at the bottom of the speaker and lo and behold, bits of the surround were easy to dislodge. If I carried on the whole lot would have crumbled away. I am inclined to order the speaker if it has all the bits I need, so I will contact Thomman. If I decide to do the job myself, I'll take plenty of photos. Cheers jJJ

I think so! Apparently the speaker has some kind of foam surrounding which, over time deteriorates and causes a flappy flatulent noise. I think this is the problem but I have found today that I'm not getting this noise with a passive bass but I do with a stingray and a flea bass. I am guessing that the two active basses put a much bigger signal in and this results in the distortion etc. even at low volumes. I emailed Gk in the USA and they suggested a new speaker was the best bet. Not quite sure what the way forward is so looking for a bit of advice. Jjj

My ~1986 GK 200MB combo has let go and now it farts and flaps and isn't the amp it used to be. I took it to the local music shop and they suggested that it was the speaker surround which is prone to decay. Has anyone bought a speaker surround kit and fitted it? How was that. There are many many screws to remove. If you have where did you get it from? Any websites / companies that may be useful? Terrible having a non functioning amp and need help! Cheers jJJ

Just joined after sneaking an occasional look at BC from time to time. Firstly my life in basses. Got my first bass nearly 30 years ago (Jedson short scale: truly awful) . then a Westone thunder 1A, natural finish. Quite playable as I remember but had the habit of breaking the little toggle switch off a few times! next '71 or '72 sunburst precision, been round the block a bit but great, chunky neck. Normal mods done on it: badass II and J bass pickup fitted (regret that mod now). next 1983 Jazz bass standard in ivory. It had EMGs fitted and a badass fitted when I got it and someone had put a metal control plate on it replacing the one piece scratch plate. Next, EB MM Stingray HH trans red MN 2006, lovely, Next EB MM Stingray 2 eq black MN 1988, lovelier! next EB MM stingray 3 eq trans red 2000 MN, lovely Finally, modulus FU metallic silver, seymour Duncan NSA aguilar, great. Basically after going slightly bonkers recently even I have to admit that I have too many and seriously need to contemplate the one in one out rule! Amps: Rubbish no name combo Big Peavey wardrobe 120w gk 200mb owned since 1987, a solid and small companion. started playing with the intention of playing in punk band with schoolmates. This turned into covers band for a few years, singer was big Cure, Bowie fan. After a very long period of dormancy and little or no advancement I started jamming with mates a bit and had a few lessons. Also looked at Scott's bass lessons website which looks good. This sort of thing has fired my enthusiasm. I may only ever be a learner and perhaps an all the gear but still no idea type of person, but bass is great and a good one is a piece of art. All the best jack
