Re. the Samsons. Ive been using one for a few years now, as has our rhythm guitarist, and although Samson claim the units deliver good sound, there is one annoying foible.
At first I thought it was just me, then perhaps my unit has a fault of some description, but only within the last few days Ive discovered it seems to be a "built in" problem.
If you hit a solo note the sound appears to "swoop in" almost like a fast acting volume pedal. It also makes the G string notes sound somewhat shallow (both wound and plain strings) And Ive noticed it on the Shadows final tour DVD where Samsons are being used.
The very first note in Theme for Young Lovers shows this effect very well. There are other points during the disc but that one is the most obvious and most easily heard.
Im surprised that Hank didnt notice this as they must have used this setup during rehearsals, but maybe they were committed to using them.
At around £200 when the show was recorded they must have been relatively expensive, but now around the £150 mark, and if you can put up with the "swoop" Maplins are selling the Samsons under their own brand name for £79.
The £2000+ units would be built to a higher (hopefully) standard
Perhaps some of the more technically minded members can put forward a theory for this effect... I personally think there is some "companding" going on to maintain S/N ratios .. a bit like Dolby processing, but have yet to find any details in print which give an answer.
