Hi Iain and Ian,
See my thread Great Strings Cheap 12-2-10. The Ampeg 600 combo is a great amp. Have one bought off ebay, B stock at £499. Used it for the first time outdoors recently and very impressed, you can get the sound you want without having to crank up the bass, mids, treble etc. It has plenty of volume at whatever tone settings you want.
Moving on from bridges to amps, Ian's 4 by 10 setup at Scarborough was also very impressive, as was Chris Jarvis's 4 by 10 rig. Any views about 15 v 4 by 10's for early Shads and 60's bass ?
By the way the Ampegs are still available on ebay at £499, the B stock one I have is as good as new and came fully packed as a brand new one. No I'm not selling them and they are not supplied by my shady Italian cousin so you can buy safely.
Regards to all, Luigi
