[TAP] switch, LED
This sets the speed of modulation-type effects such as Chorus or Flanger, or the time
of Delay or Tape Echo effects. The interval between two presses of the switch will be
set as the time. The LED will blink at intervals of the specified speed or time.
HINT: To set a precise time that matches the tempo of a song, press the
switch several times in rhythm with the song.
HINT: You can also adjust the speed or time setting by holding down the
[TAP] switch and turning the [EDIT] knob (EDIT 2).
NOTE: You can't use the [TAP] switch to set the time while the BYPASS LED
is lit. The TAP LED will be unlit.
[BYPASS] switch, LED
If you don't want to use an effect, press this switch to turn off (bypass) the effect. This
LED will be lit if the effect is bypassed.
NOTE: Pressing this switch will not bypass the reverb. If you don't want to
use reverb, turn the [REVERB] knob all the way to the left so that the mix
amount is 0.
NOTE: You can't adjust effect parameters while the BYPASS LED is lit.
HINT: When the effect is bypassed, you can adjust the noise reduction sen-
sitivity by holding down the [TAP] switch and turning the [EDIT] knob.
HINT: The bypass setting is remembered even when you switch modes or
programs, or when you turn off the power.
[PRESET] switch, LED
Use this to switch to Preset mode, and to select preset programs (P1: basic, P2: ef-
fected, P3: song). In Preset mode you can use the [AMP] switch/selector to select
typical sounds (preset programs) for each amp model. The LED will be lit green,
orange, or red when you're in Preset mode.
[MANUAL] switch, LED
Use this to switch to Manual mode. In Manual mode, the sound will reflect the physical
position of all of the knobs except for the [EDIT] knob. This lets you use the VT15/30
just as if it was a conventional guitar amp. The LED will be lit when you're in Manual
mode.
[BANK] switch, LED
Use this to select the channel bank. In Channel Select mode, the bank LED will be lit
green or red. If you want to save a new program in a different bank, hold down the
[BANK] switch for 0.5 seconds or longer (until the BANK LED starts blinking) and
select the desired writing-destination bank (p.15 "Saving a program").
