Hi guys!!!
i want to buy this one but i have a doubt. it's about cavity neck... somebody knows the measures? i want to put a maple soft "v" neck... what do you think about it? my stratocaster replica have Clapton mid boost and noiseless and i will put my pickguard on the powerhouse. this one have the same cavity to the mid boost as Clapton's stratocaster?
thanks in advance.

Both guitars use the same cavity for the "Elite" PCB.

The Powerhouse's mid-boost circuit is the same as the Clapton, except the gain is reduced to 12dB by a pair of resistors and the TBX pot is replaced by a No-Load tone circuit. Clip the resistors to unlock the full 25dB boost, remove the stock pickups with the dummy coil & No-Load pot and stick a set of Vintage Noiseless pickups with the TBX, there's not necessary to replace the PCB.

but you know if this Vintage V Neck MM 2902V Mighty Mite will fit? thank you for your reply.

Certainly.

Mighty Mite necks could fit into almost any standard Strat body - unless you decide putting them into either a 70s 3-bolt or an American Deluxe body, then some alterations may be required.
