Thanks guys.
Ill answer the questions in order..........
I leave the cabinet simulation "on". The reason for this is simple. All combo amps get their sound from a combination of things mainly the pre amp, power amp and speaker enclosure. Im running a very clean 100watts of power with massive amounts of headroom. This should hopefully not interfere with the sound that the VAmp produces. Basically just treating my amp like a full range P.A system. I must say it works extremely well.
I just made the amps with RCA inputs and custom made the leads to suit. 1/4 inch guitar style connector to male RCA connector. Makes it easy to tinker with if I ever need to disassemble the unit.
Total cost was as follows in Australian dollars:-
$50 for the 16mm MDF all cut to exact size.
$40 for Blue Tolex. (Automotive Upholsterer)
$18 for a jumbo can of 3M spray adhesive.
$10 for assorted screws, cup washers etc....
$7 for a strap handle (not fitted yet.........its off getting chrome plated)
$7.50 for 4 small castors for the bottom.
$24.95 for each amplifier From Jaycar Electronics.
$35 for the power supplies.
$3 for the white piping around the case.
$18 for a 10mm radius Router bit.
$5 for a packet of staples.
Total of $218.45
Plust the cost of the VAmp Pro. (which I allready had.)
Most of the stuff I already had so it really didnt cost me anything.
I allowed $50 for the supply and cutting of the MDF although it cost me nothing to cut it myself.
The white tubing id called piping. Its used by upholsterers in car seats and such.
The amp is permanently on when the mains power is plugged in. Being a Mosfet amp, it draws a tiny tiny amount of current and produces no heat or noise when there is no input. The volume control is on the right hand side of the VAmp pro..............labeled Master Volume.
