Just being honest here. For the life of me I can't understand why anyone would buy a guitar with the intentions of modding it. I can understand if you had a bass for a while, years, and decided maybe I'll upgrade the pickups or whatever. But, to buy a bass with intentions to immediately mod it???? Why not just find the bass that you're looking for and be done with it? Lets say you spend $300.00 on a bass, buy another 300.00 worth of upgrades, and pay for labor on top of that. Why not just save the money and buy the bass you're after? I'm mostly referring to mods that effect sound or playability.
I don't know I just had to post this because I seriously don't get it. Is it just a hobbyist thing?
Simply put, more often than not what you want just isn't available. I'll give you my example.
When I bought my Squier Affinity Jazz Bass, I did so for 2 reasons, and they both related to the woodwork. I LOVED (and still do) the feel of the neck. The run of Affinity J's had well dressed frets, the neck is fast, and smooth as a baby's backside. I also like the slightly thinner body of the Affinity series, nice and light. And lastly, I wanted a Burgundy Mist Jazz, which the Affinity series was my only option.
Pickups wise, I wanted the Duncan Designed jazz pickups from the first generation Vintage Modified series. I just love the sound of them...
Bridge wise, I wanted a high mass bridge, but with a classic, brass touch of the Classic Vibe 60s bridge.
And lastly, OEM pickguards blow chunks in most cases.
To get what I wanted, I had to mod, I couldn't even try to pay the custom shop to get what I wanted. They just don't offer it...
My pending mod is on an SX Ursa 3. Simply put, I want a passive PJ bass in 3 tone sunburst, with an alder body, a fretless neck but with a maple fingerboard. I can get everything but the maple and Alder with the Squier Vintage Modified PJ Fretless, for $299.99, and it still wouldn't be right.
For $149.99 I can get an SX Ursa 3 RN ALD 3TS, and the neck is unimportant as I alredy have an SX Ursa 1 MN FL neck (Maple Fingerboard Fretless). The neck cost me $30.00
And lastly the pickguard. I am a big fan of antique white pearl on sunburst finishes. I can get a pickguard that requires VERY minimal trimming to fit for $12.00
So for less than $200.00, and with a little bit of my time, and effort, I get EXACTLY the instrument I want, instead of paying someone else a couple of grand to get what I want... I'm not that rich, and honestly I love tinkering...
