So many to choose from depending on your choice of flavours. How about Malmesbury Abbey, St Mary Bridgnorth, St Nicholas Kings Lynn, St Mary Little Walsingham, St George Letchworth, University of Sussex meeting house, Farnborough Abbey, St Nicholas Gosforth or for 2 manuals +1 St Mary Beaminster.
This organ in Stratford-upon-Avon is regarded, rightly in my view, as being able to fulfil most requirements in this rather dead acoustic. There may be a fair amount of extension but space in the chapel's west end tower is limited.
HTH
Can anyone recommend some existing specifications to look at. Parameters are
1. two manuals
2. able to give a beefy accompaniment to a full congregation in a relatively dead acoustic
3. extensions allowed (within reason)
Thanks.....
