Superb quality Roland rack guitar pre-amp featuring a twin gain-staging overdrive and all-discrete three band eq. There’s an effects insert after the overdrive and another after the eq. Perfect for use as a flexible guitar DI or put in front of your amp. Awesome design and build quality (see Tone Report blog excerpt below).
In very good condition, serviced and ready for action.
It is a 100v Japanese model and will run fine on North American mains 115/120v without a transformer (we run all our tests using 120v power); however, a step-down transformer is recommended for extended use.
A step-down transformer is required in the UK/EU.
We do not recommend using cheap generic Chinese mains transformers and can supply a high quality UK-made unit if required.
For sales in UK/EU the price will include VAT. VAT-free sales are possible to businesses and individuals in the EU (outside the UK) with a valid VAT Number – please get in touch if you wish to buy this way.
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.”
