With a lot of people listening to music from their phones and YouTube, we have decided to start incorporating tone controls (Bass, Midrange, Treble) into future preamplifiers. Of course, there is also a bypass switch to take the tone control circuit out of the signal path.
The unit below is for sale. It is a custom built Spirit 1 12AU7 Linestage with Bluetooth as well as using tone controls and a balance control as well as a tone control bypass switch. Black Gate power supply filter capacitors and Clarity Cap output capacitors.
Asking $1,050 including shipping to lower 48 to anyone who see tbis ad. ($1,250 on website)
Full Details about this preamp can be seen on our specials page.
