Product Description
Roland SIP-300 for sale. These are not common and are an awesome piece of Roland design and build quality (see Tone Report blog excerpt below).
Serviced including power supply recap and swapping out a couple of dead sockets. Ready for action.
From The Tone Report blog:"These units were released in 1980, and were touted as “preamp” units even though they contain other effects. The SIP-300 is the guitar version, and features a footswitchable overdrive circuit, while the SIP-301 is the bass version, featuring one of the juiciest compressors ever released. These SIP units barely count as multi-effects since they only include two effects, but they provide enough versatility in their EQ sections to make the cut. The equalizers are a three-band type, with arrays of cut and boost switches, as well as a mids switch that sets the specific frequency of the midrange: the SIP-300 offers 1kHz or 500Hz switching, whereas the 301 offers 250 or 500Hz. The overdrive circuit on the 300 is interesting; it features two cascading gain stages with only a volume knob for both. When stacked in front of a hungry power amp, this can be devastating. Both units feature a choice of unbalanced or balanced outputs, as well as an effects loop. Both are fairly rare—the 301 being more so—but are certainly worth seeking out."
