Andy Fuchs | you don't need all that..... The average guitar amp input stage offers an adequate amount of gain at a reasonable level of noise. To gain a true benefit of balanced inputs, you would really need a balanced source. Okay, so center tap your pickups.... But seriously, switch the first tube to a 2SK30 ultra hi mu fet, and ditch the tube maybe. Perhaps parallel the 12AX7 halfs, and reduce the gain back to where one tube was (and buy some noise db's). But cascodes are super sensitive to outside world noises (I've tried them), and they amplify the capacitance of the input source, so your cables 'sound' will become an issue. |
