About a few months ago i bought one of those new dean 'evil d' signature basses. Retails for around $1300 aud. The sound of the thing was really awesome, aggressive as hell, and growled like a lion, but... that was the only good thing, i was very dissapointed, the neck was crap, kept moving and going out of wack within an hour of being adjusted, the fretwork was crap, no matter how many times my local guitar shop adjusted the neck, there was fret buzz nearly everywhere, even if the guys managed to get rid of the fret buzz in the 1st to 8th fret, there was always really bad fret buzz past that, it could never be fixed. Was horrible. And to top it all off, it was equipped with one of those 2 peice (saddle and tailpeice (i think thats what you call them) were seperate) warwick bridges that you can find on like $7000 aud warwick basses. I thought this bridge was going to be awesome, the bridge just fell apart, the saddles kept coming loose, the strings would just flop off, was amazingly CRAP.
I was soooo dissapointed beyond beleif, so i traded it in for a Cort B4 ($300 aud cheaper), and can i tell you, the cort craps all over the dean, even though the cort was alot cheaper than the dean, it is sooo much better.
Therefore, from my story above, you can probably guess i am pretty much against dean. Except...the guitarist for my band just recently bought a dean hardtail (rrp around $1700aud), and it is REALLY good. And dean does have a good reputation for there guitars, but i havnt heard anything special about there basses.
