I've been (pardon the pun) out of the loop for a few months, indeed
since the first appearance o'the Line6 DL4.
For those without long and detailed memories, I loop by putting a Jam-Man
in delay mode, with single repeat, in a hardwired loop (o/p-i/p) with a
volume pedal in't to control the feedback. The system works well, but 'tis
none too efficient having a 19" rack box on the floor, basically acting
like a huge great glorified stompbox (ie a taptempo 32 sec delay).
Anyhow, out has come the DL4. And much verbiage has been verbed about it
(how come when I'm on this list I start wtriting like dt?) but questions
the size of Texas yet remain. Chief among them are:
1. Can it be set to just an ordinary, tap-tempo, 14-sec delay?
2. I hear it's stereo. Is that 14-sec, looped stereo?
3. Half-speed mode. Does it sound any good?
4. Can you change the delay length on the fly? Not change the speed. On
JamMan, as configured, tapping a new loop when one is already playing
in the looping of just the segment that was playing between the taps
Or is it like the JM in Loop mode - once tapped, the tap button becomes
5. Can you use the EXP-pedal inputs (I hear they're there) to control
output level and feedback?
I've looked at the online manual and suspect I know the answer to some of
these, but thought I'd better ask the experts. I think it looks
unpromising (No feedback control!!!) but best to be sure.
Why oh why can't someone make a simple 20-second taptempo stompbox??
PS Those with gargantuan, nay behemothian, mamories will recall much
discussions about (a) guitar resonances and (b) possible avenues for
guitar-related research. Such individuals might be glad to know that I've
got a few research projects on the acoustics of electric guitars on the go,
and such projects seem to be building up a head of steam. And all this
from a debate, on these very pages about 18 months ago, between myself, our
moderator and Matthias Grob about whether resonance was good or bad for
