G, interesting... you say that you have a light touch... I guess that must be it then, as I already mentioned.
Well, when I was a teenage, I took a 1 year off bass lessons, 1 hour a week only and my bass frets were such in bad shape that I had to de-fret it myself, but once a week I'd use the teacher nice bass, and Bernard (my teacher) was a double bass concert player.
I remember him saying to me: pluck harder, pluck harder... pluck harder... Gino, pluck harder.... Well you guessed? I had to pluck hard!
What now, well I realized that on a poor instrument with bad frets you have to have a higher action, and you have to pluck harder on passive basses, especially when you don't have an amp. At that time, I hacked my little radio which had an input for microphone, and made up a custom jack to get the bass going thru... further, I got hold of a cheesy speaker (better then nothing) and I built a cabinet out of my bedside table! Well, I was 15/16 and was happy (I am still). Further... I found that good instruments with good frets (shape/condition) and good amplification allows you to have a much softer action.
I wasn't lucky enough in that respect, until I came across the Aria SBs, and while we can call them the poor man's bass, it has been a like finding a treasure for me. As I have played fretted bass after my first de-fretted, all needed high action/harder pluck.
The other day, at the bass centre, when I collected my Arialembic from Chris, he plug the fing in the amp, and GOD, the sound was so HUGE for me, I couldn't play, I had to cut everything on the amp, including the gain and so on... I saw that the other guys were touching the bass, and I though, I know why know... So, I think the Alembic is very well suited, or indeed designed for feather touch, and the cheaper bass are for the hard working man if I may.
OK guys, I hope I didn't bother you too much with my stories
Well, this in an interesting story I think, it says that if you start early on a poor instrument that requires hard plucking, you keep habits, and when you play the fine instruments, you are a bit lost and confused! Ok, I'll rephrase and add something; I do like the harder pluck, and I don't regret having to learn on the bass I had, because it has been good experience, and I strongly feel that it is easier to switch from hard to soft pluck than soft to hard...maybe I am wrong?
