Hi, :)
I have pondered this one for a while, as my use of a Lucille, would be ( not surprisingly ) as a mellow , sweet Blueser. I nearly wept, when you told me what she was going to be used for . :lol: I certainly agree about the 490/498s being very nondescript for such a desirable guitar. Mules replaced mine in the Les Paul - and the rest is history. I do not own a Lucille - but have admired them from afar..
Right ; back to the main question - for which I an definately thinking Riff Raffs .
"Old School Rock tone with a grunt in the bridge ". Especially with your 'Varitone' switch, and feedback proof ( but warmer sounding) body . I do not own a set of R.R.s - but have heard them, and therefore am imagining the sonic balance achieved with that combination.
(* Further edit *)
Do check with Tim at B.K.P - as I cam not sure whether Riff Raffs will give you " Grunt" or " Spank" in the bridge.
Do let us know what you end up deciding / are 'prescibed' by Tim. :)
