Tape recorder techniques

[syntheticwaste@xxxxxxxxxxxx]

I have some questions about the different 
techniques in manipulation of the magnetic 
tape. Me and a friend is currently working 
with splicing and cutting tape. We utilize 
these ways of manipulating; change of speed, 
direction, and delay. Here in his studio, we 
have only one tape recorder right now, an 
old 2 track. However, I am aware of effects, 
like reverb, made by the use of tape loops 
only. I would like to ask how this is done, 
and also how many tape recorders would be 
the minimum for this and similar effects 
that is possible with the use of tape.
The only sound sources for this piece we are 
planning and setting up for recording, is 
the sound of 7 glasses with different 
amounts of water, resonanting, and then we 
put the glasses on a hard surface; the 
surface is connected with two contact mics, 
one for each channel -left and right. What 
type of surface would be best fitted for 
this? We are thinking of a thick glass 
surface... Any help and/or comments on all 
of this will be highly appreciated. Thanks!
