I just starting working with a producer who works with name pop artists, and the songs are much more produced than what I'm used to - it's much more about timbres... So I recently overhauled my 5-string Jazz when I became dissatisfied with its recorded sound. I also have a Dean Edge 5 that I thought was great - always mixes well for shows and it's the best playing bass I've ever touched - I mean by far - some kind of magic; the string heights at the twelfth fret are the same as on my best 6 string guitars. Also this is the only bass I have a ramp on, which makes things so much easier and more precise... But working with this pop guy, I haven't used anything but my old 4-string Cirrus and a cheap Epiphone Beatle bass I got from Guitar Center for $225 LOL. They just sit perfectly in the mix and don't need much tweaking to mix. Also I have learned to imitate the Beatle bass with my Cirrus. It strikes me as I listen back to my attempts to record with 5 string basses that it's the fifth string that doesn't fit in. It really sounds like a clam or another instrument. I tried Cirlce K strings, which helped a great deal but it is still very obvious when I move to the 5th string, even adjusting technique and all (btw been playing for 30 years and have a bachelor's for [classical] guitar performance). I just can't deal with it. I kinda decided to part out my 5 string basses but I'm dragging my feet on that because I'm attached to them. Also I don't really like retuning my Cirrus for every tune for recording - or going with the ridiculous mudfest EQ for live R&B so all the Eb's don't sound like the bottom dropped out... But for now I'm a four string guy. Grudgingly. Also I have started to gather parts and raw materials for a 7-string multiscale build, using the same maple/purpleheart combo as my Cirrus and the same scale at the A string, so hopefully that will cure my problems. All I have done so far is glue up the main plank - the neck/core. And buy some hardware and electronics... I'm doing 7 strings because I double on guitar, but I tune my guitar like the top 6 of a 7 string (EADGCF), so I figure it will be an easy transition. Plus I don't really enjoy building anywhere near as much as I enjoy having instruments that work correctly - I don't want to have to do this again a few years LOL. Anyone else kinda get forced back into 4-string? Anyone else think that a single scale 5 string is just an unworkable, unusable design?
