The sound ? this is all my opinion.What is the sound that we are after ? can we remember the first "the sound" that we had ?,are we trying to re-create this ? or are we trying to re-create someone elses sound ? when i switched from guitar to bass i carried on using my guitar amp and cab,Selmer Treble & Bass 100w & 4x12 cab with my 68 Precision.I thought it was a great sound.I have been swayed by other basses and certainly other amps/cabs,combos,but still get the same sound out of my current set up,especially since Howard built me a bass to replicate that 68 P bass.I have tried to use a more hi - fi sound with both basses and amps but have never been truly happy with the result.I have spent an absolute fortune in the last 20 years or so on gear to get "that sound",but realised that,
1,an amp/speakers make just as much,if not more difference to the sound than a bass does.
2,technique plays a much bigger role in shaping the sound.
3,the cost of equipment does not always justify the end result.
4,If you are looking to replicate someone elses sound,pay more attention to their technique than their gear.
